Solution:
A rigid body executes both translatory and rotatory motion. When acted upon by unbalanced torque, a rigid body executes pure rotational motion. i.e., angular velocity of all particles remain same during rotation
Statement (A) : A rigid body executes both translatory and rotatory motion
Statement (B) : A rigid body executes pure rotational motion when it is acted upon by an unbalanced torque
A rigid body executes both translatory and rotatory motion. When acted upon by unbalanced torque, a rigid body executes pure rotational motion. i.e., angular velocity of all particles remain same during rotation
