A body of mass m is performing a UCM in a circle of a radius r with speed v. The work done by the centripetal force in moving it through rd of the circular path is
- A Zero
- B
- C
- D
Answer & Solution
Correct Answer
(A) Zero
Step-by-step Solution
Detailed explanation
When a body perform uniform circular motion, then centripetal force acts always in perpendicular, direction to its velocity, hence work done by centripetal force is always zero.
Hence, work done by centripetal force is zero, when it through rd of the circular path.
Hence, work done by centripetal force is zero, when it through rd of the circular path.
