Consider the following statements and select the correct option which identifies true (T) and false (F).
(i) When a body thrown up, its kinetic energy gradually changes into potential energy.
(ii) When a body falls from a certain height, its potential energy remains the same.
(iii) Work done by friction over a closed path is zero.

A

`{:("(i)","(ii)","(iii)"),(T,F,T):}`

B

`{:("(i)","(ii)","(iii)"),(F,T,F):}`

C

`{:("(i)","(ii)","(iii)"),(T,F,T):}`

D

`{:("(i)","(ii)","(iii)"),(F,F,T):}`

Text Solution

Verified by Experts

The correct Answer is:
C
When a body falls from a certain height, its potential energy gradually changes into kinetic energy. Friction is a non-conservative force. Work done by a non conservative force over a closed path is not zero. Hence, option (C) is a false statement.
