A thin walled hollow spherical shell of mass m and radius r starts from rest and moves along atrack as shown in figure assume that shell successfully negotiates the loop.
Statement-1: Normal reaction at A is greater when friction is absent on the track as compared to the case when sphere executes pure rolling.
Statement-2: Due to frictional torque shell have larger translational velocity at A in case of pure rolling.
A. Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
B. Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1.
C. Statement-1 is true, statement-2 is false.
D. Statement -1 is false, statement -2 is true.
