Answer 1

SOLⁿ ::

IF BALL COMES OUT FROM BIGGER LOOP THEN IT WILL COME OUT FROM THE GIVEN RIGID BODY,,,,

SO NOW WE HERVE TO SOLVE THAT WHAT MINIMUM VELOCITY REQUIRED TO CROSS BIGGER LOOP??

ENERGY CONSERVATION FOR BIGGER LOOP,

K1 + U1 = K2 + U2

½MV² + 0 = 0 + MGH

½MV² = 4MGR { BECAUSE OF (H = 4R)}

V² = 8GR

V = √8GR

SO HERE OPTION "B" IS RIGHT ANSWER....

HOPE IT HELPS..
