Question

The angle of inclination between two vectors P and Q is theta.
If P and Q are interchanged in position show that the resultant will

Answer 1

Explanation:

If both the forces interchange their position as well as directions with each other, there would be no change in resultant. As the measure of angle would be same ie ` theta,` the resultant would be unchanged/ same ie.[P^2+Q^2+2PQcos(theta)]^1/2.
