When a body moves with a constant speed along a circle

Options

  1. Ano acceleration is produced on the body
  2. Bno work is done on it
  3. Cits velocity remains constant
  4. Dno force acts on the body

Correct answer

B. no work is done on it

Step-by-step solution

When a body moves with constant speed v along a circle, it has a centripetal acceleration but no linear acceleration. The centripetal force F acting on the body is at right angle to the displacement s. Since, aligned W & =F s=F s & =0 ( 90^ =0 ) aligned Hence, no work is done on it.
