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.
Is gravitational potential a scalal or vecror quantity?
Gravitational potential is a scalar quantity. It represents the amount of energy per unit mass at a point in a gravitational field. When considering gravitational potential, only the magnitude of the potential is important, not its direction.
Why there will be a point between the earth and the moon at which the gravitational field strength will be zero?
At a point between the Earth and the Moon where the gravitational field strength is zero, the gravitational pull from the Earth and the Moon cancels out, resulting in a net force of zero. This point is known as the L1 Lagrange point, where the gravitational forces are balanced due to the interaction between the gravitational pull of the Earth and the Moon.
What is the unit of measuring gravitational field strength?
The unit of measuring gravitational field strength is Newtons per kilogram (N/kg). It represents the force exerted on a unit mass at a particular point in a gravitational field.
Can gravitational be added to electric field to get the total field?
Yes, gravitational and electric fields can be added together to get the total field at a point if the two fields are acting on the same object. The principle is known as superposition of fields.
How is the magnitude of an electric field defined?
The magnitude of an electric field is defined as the force per unit charge experienced by a test charge placed in the field. It is measured in units of newtons per coulomb (N/C). This magnitude represents the strength of the electric field at a particular point.
What is the reference point for gravitational potential energy?
The reference point for gravitational potential energy is typically set to be at an infinite distance away from the gravitational field, where the potential energy is considered to be zero. This allows for the calculation of the change in potential energy as an object moves within the field.
What is the definition of a gravity force field?
A gravity force field is a region of space where objects with mass experience a force of attraction towards a central mass, such as a planet or a star. This force is what causes objects to be pulled towards the center of the field, like how Earth's gravity keeps us grounded.
How closely packed the electric field lines are indicates the strength of the electric field?
true
What is meant by gravitational field strength?
Gravitational field strength represents the intensity of the gravitational force experienced by an object at a specific point in space. It is a measure of how strong the force of gravity is at that location and is typically expressed in units of newtons per kilogram. A greater field strength indicates a stronger gravitational pull on objects placed within that field.
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.
What is difference between gravitational potential energy and gravitational potential?
Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, while gravitational potential is the potential energy an object has per unit mass at a particular location in a gravitational field. Gravitational potential depends on the mass of the object while gravitational potential energy depends on the object's mass and position.
Why is a magnetic field a vector quantity?
Magnetism is a force. Vector notation is required to indicate magnitude and direction of a force.
