1) Centripetal and centrifugal force on the object is equal and opposite, so both cancel each other and net force is zero.
2) The velocity constantly changes, and change in velocity cannot be zero and change is towards the center , thus acceleration cannot be zero since a=change in velocity/change in time, that means net force is in the direction towards the center( because direction of force is same as direction of acceleration.)
3) If Net force is non zero, why doesn't object goes to the center?
