What is the magnitude of the gravitational field 2.00m from a 5.00kg point mass?

I'm a little rusty on my physics, but this question does not provide enough information to answer.
The strength of a gravitational field (according to Newtonian physics, at least) is a function of two interacting masses and the distance between those two interacting masses.
Newton's law of universal gravitation is:
F = G * m1 * m2 / r^2
where:
G is the gravitational constant
m1 is the mass of the first point object
m2 is the mass of the second point object
r is the distance between the two point objects
So presuming that the SECOND point object has the same mass as the first point object (5.00kg for both), then your answer will be:
6.674 * 10^-11 * 5 * 5 / 2^2 = 4.17 * 10 ^-10 Newtons.
You will note that this shows us that gravity is an incredibly weak force - EASILY the weakest of the four fundamental forces in the universe.

What is the law of gravitational potential energy?
Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount.
Why is the size of a decimal number not necessarily determined by the number of decimal places notated?
Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude.

Is electric field strength scalar or vector?
The strength of the electric field is a scalar quantity. But it's the magnitude of thecomplete electric field vector.At any point in space, the electric field vector is the strength of the force, and thedirection in which it points, that would be felt by a tiny positive charge located there.
How does estimating help us place the decimal point in the quotient?
Estimating will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude.
What does moving a decimal point change?
The magnitude or value of the number.
Why there will be a point between the earth and the moon at which the gravitational field strength will be zero?
There is a point where the gravitational field strength of both planet or object is equal, hence they cancel off each other, resulting in zero net gravitational field strength.
What is the definition of a gravity force field?
A gravitational field is the force field that exists in the space around every mass or group of masses. This field extends out in all directions, but the magnitude of the gravitational force decreases as the distance from the object increases. It is measured in units of force per mass, usually newtons per kilogram (N/kg). A gravitational field is a type of force field and is analogous to electric and magnetic fields for electrically charged particles and magnets, respectively. There are two ways of showing the gravitational field around an object: with arrows and with field lines. Both of these are shown in the picture below. Arrows show the magnitude and direction of the force at different points in space. The longer the arrow, the greater the magnitude. Field lines show the direction the force would act on an object placed at that point in space. The magnitude of the field is represented by the spacing of the lines. The closer the lines are to each other, the higher the magnitude. The gravitational field varies slightly at the earth's surface. For example, the field is slightly stronger than average over subterranean lead deposits. Large caverns that may be filled with natural gas have a slightly weaker gravitational field. Geologists and prospectors of oil and minerals make precise measurements of the earth's gravitational field to predict what may be beneath the surface. Website Name : INshortkhabar
What is difference between gravitational potential energy and gravitational potential?
A body A of mass m is placed in the gravitational field of a body B of mass M. The gravitational potential of body B at a point in the field is the work done is bringing unit mass from infinity to that point and is independent of body A. On the other hand, the gravitational potential energy of body A is the energy possessed by it due to its position in the field. In fact, Gravitational potential energy = mass of body(A) x gravitational potential
What does not effect the pressure at a point beneath the surface of a liquid?
strength of gravitational field
Why should an test charge be of negligibly smaller magnitude?
The magnitude of the test charge must be small enough so that it does not disturb the distribution of the charges whose electric field we wish to measure otherwise the measured field will be different from the actual field.

Gravitational energy is the potential energy associated with gravitational force. If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount.
What is a magnetic field vector?
It is a way of representing the magnetic force at a point in the field. The magnitude and direction of the vector represents the strength and the direction of the magnetic force acting on a charged particle in the field.
How much mass does a celestial object have to have to exert gravitational force?
There is no minimum mass at which point an object (celestial or otherwise) begins to have a gravitational force. Any object with mass has an associated gravitational force. The magnitude of that force is proportional to to the mass of the object - lots of mass results in lots of gravitational force; little masses result in only little gravitational force.
