Q. Torque applied on a particle is zero, then its angular momentum will be
A) Equal in direction
B) Equal in magnitude
C) Both (a) and (b)
D) Neither (a) nor (b)
Explanation
(c) $\overrightarrow{\tau} = \frac{d\overrightarrow{L}}{dt}$, if $\tau = 0$ then $\overrightarrow{L} =$ constant $i.e.\ L$ remains constant in magnitude and as well as in direction
