An object moving in a circle at constant speed (Choose a correct option with some nice explanation!) a) must have only one force acting on it.
b) is not accelerating.
c) is held to its path by centrifugal force.
d) has an acceleration of constant magnitude.

ABSURB ANSWERS ARE GONNA GET REPORTED. THAT'S IT

an object is moving at constant speed then it has no acceleration.

Explanation:

This is indeed true in the case of an object moving along a straight line path. On the other hand, a particle moving on a curved path is accelerating whether the speed is changing or not. Velocity has both magnitude and direction.

But Than Again when a object moves in a circle at a constant speed its velocity (which is a vector) is constantly changing. Its velocity is changing not because the magnitude of the velocity is changing but because its direction is.
