Question

What can be the angle between $(\vec{P} + \vec{Q}) and \vec{(P} - \vec{Q})$ ?

Moderate

A

$90^{0}$
B

$0^{0} only$
C

any angle between $0^{0} and 180^{0}$
D

$180^{0} only$

Solution

$β is the angle between$ $\vec{P} + \vec{Q} and \vec{P} - \vec{Q} . β$ can have any value from $0^{0} t o 180^{0}$
depending upon magnitudes of $\vec{P} and \vec{Q}$ and angle $θ$ between them.
