Question

for an object to move in uniform circular motion it is necessary to have ?
a) zero net force
b) net force in the radial inward direction
c) net force in the radial outward direction
d) net force in tangential direction
​

Answer 1

The direction of the net force is in the same direction as the acceleration. So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration.

Answer 2

Answer:

c. net force in the radial out ward diretion
