1. 24
2. 23
3. 12
4. 11

Q. A particle is moving with a uniform speed $v$ in a circular path of radius $r$ with the centre at $O$. When the particle moves from a point $P$ to $Q$ on the circle such that $\angle POQ=\theta$, then the magnitude of the change in velocity is

1. $2v\sin \left(2\theta \right)$
2. zero
3. $2v\sin \left(\theta /2\right)$
4. $2v\cos \left(\theta /2\right)$

Q. A boy throws a ball to his friend $20\text{m}$ away. The ball reaches to the friend in $4\text{s}$. The friend then throws the ball back to boy and it reaches the boy in $5\text{s}$. Assume the ball travels with constant velocity during any throw.

1. The average velocity is $\frac{40}{9}{\text{ms}}^{-1}$
2. The average acceleration is zero.
3. The average velocity is zero but average acceleration is non-zero.
4. Average acceleration of the motion cannot be defined.
