Question 2. A small body attached at the end of an inextensible string completes a vertical circle, then its (a) angular momentum remains constant (b) linear momentum remains constant (c) angular velocity remains constant (d) total mechanical energy remains constant
A small body attached at the end of an inextensible string completes a vertical circle, then its. Explanation: Whenever a body is released from height, it travels vertically downward towards the surface of earth. This is due to the force of gravitational attraction exterted on body by the earth.
