Question

A simple pendulum consisting of a ball of mass m is tied to a spring of length / is made to swing on a circular arc of angel $\theta$ in a vertical plane. At the end of this arc, another ball of mass m is placed at rest . The momentum transferred to this ball at rest by the swinging ball is

• A. Zero
• B. $m\theta \sqrt{\frac{g}{l}}$
• C. $\frac{m\theta }{l}\sqrt{\frac{l}{g}}$
• D. $\frac{m}{l}2\pi \sqrt{\frac{l}{g}}$

Answer 1

The correct option is A Zero

No momentum will be transferred at the extreme position because, at extreme position the velocity of bob is zero.
