**Question:**

**Choose the correct alternatives:**

**(a) for a general rotational motion, angular momentum L and angular velocity ω need not be parallel**

**(b) for a rotational motion about a fixed axis, angular momentum L and angular velocity ω are always parallel**

**(c) for a general translational motion, momentum p and velocity v is always parallel**

**(d) for a general translational motion, acceleration a and velocity v are always parallel**

**Solution:**

The correct answer is

(a) for a general rotational motion, angular momentum L and angular velocity ω need not be parallel

(c) for a general translational motion, momentum p and velocity v is always parallel
