.What can be the angle between P vector + Q vector and p vector - q vector

Answer»

ANSWER:

The angle between P VECTOR + Q vector is 0° while the angle between P vector - Q vector is 180°.

Since RESULTANT vector=√P^2 vector +Q^2 vector +2PQvector cos 0°. (cos 0°=1 and cos 180°=-1)

HOPE THIS HELPS..☺️
