Q127 / 160 · TS EAMCET 2021 (06 Aug Shift 2) · Physics

In uniform circular motion, which of the following statement is wrong?

A
Work done during one complete cycle is zero.
B
Centripetal force acting towards the centre of circle.
C
Angular velocity is constant.
Correct answer
D
Tangential velocity is constant.

Solution

In uniform circular motion, we have the following properties (a) Work done during one complete cycle is zero. (b) Centripetal force acts towards the centre of the circle. (c) Angular velocity is constant. (d) Speed is constant but not the tangential velocity because its direction changes continuously. $\therefore$ Tangential velocity is not constant.

Hence, the correct answer is option: 'D'.
