### Solution:

We know that a body performing uniform motion in straight line will continue to move along due to inertia of motion (i.e. according to Newton’s first law) so external force is

not required. But to move a body uniformly along a circular path. We need to change its

direction at every point along the circular path. Therefore force is needed to act on a body at every point.

So we get statement (A) is false but statement (B) is true
