MCQ

B

C

✓

✓

Answer

Correct option: D.

Both acceleration and speed are constant

For a body moving in uniform circular motion the speed attained by the object will remain constant not the velocity as velocity depends on the direction of motion, and in circular motion the direction of the object changes at every point.
As speed remains constant the acceleration will remain constant.
