A ball moves along an uneven horizontal road with fixed speed at all points on the road. The normal reaction of the road on the body at two different points A and B is
Text Solution
Verified by ExpertsThe correct answer is:
C
Centripetal acceleration at A and B is 
and 
espectively. Clearly r B > r A . therefore, centripetal acceleration at A is more. Thus, reaction at B is less than A because here the normal reaction depends on upwards force or acceleration.
