If the two vectors are in the form: P = ai + bj, and Q = ci + dj

Then the resultant vector is (a + c)i + (b + d)jand the magnitude is:

sqrt((a +c)2 + (b + d)2)

If 3 dimensional, then the k components are added then squared and added to the i & j components, before taking the square root.

How great is the resultant of two equal-magnitude vectors at right angles to each other?

Let two equal magnitude vectors be 'X'.. Then, resultant=1.414X


Can the resultant of two vectors of the same magnitude be equal to the magnitude of either of the vector proof mathematically?

Yes. If the two vectors are two sides of an equilateral triangle, then the resultant is the third side and therefore equal in magnitude.


If the sum of the two unit vectors is also a unit vector find the magnitude of their difference?

resultant


What is the magnitude of the two vectors having a sum of zero?

If their sum (resultant) is 0, then the magnitude of the resultant must be 0.


Can the resultant of two vectors of the same magnitude be equal to the magnitude of either of the vector. How?

Yes - if the vectors are at an angle of 60 degrees. In that case, the two vectors, and the resultant, form an equilateral triangle.Yes - if the vectors are at an angle of 60 degrees.

Can the magnitude of resultant of two vectors of the same magnitude be equal of magnitude of either vector?

yes


Can the resultant of two equal vectors be of same magnitude as the two vectors?

Yes. This will happen if the two vectors are at an angle of 120 degrees.


What should be the angle between two vectors of magnitudes 8 and 8 units so that their resultant has a magnitude of 20 units?

It is not possible. The maximum magnitude is obtained when the vectors are aligned and in this case the resultant has a magnitude which is the sum of the individual vectors. In the given example, the maximum possible magnitude for the resultant is 16 units. In general |a+b| <= |a| + |b| where a, b are vectors and |a| is the magnitude of a


Does the resultant take into account the direction of the two vectors?

Yes, a resultant vector is the vector sum of the two vectors. It has it's own direction and magnitude.


Two vectors of equal magnitude have got a resultant whose magitude is equal to either one of them. Find the angle between the two vectors?

120 deg


When two vectors are added and their magnitude is equal to the magnitude of resultan what will be angle in between them?

if you add the vectors magnitude and equal to resultant the angle between them is 0


Can the resultant of two vectors be 0 how is it possible for two vectors always?

If they are equal in magnitude but act in opposite directions.
