A solid sphere rolls down two different inclined planes of the same height but of different inclinations

A

Speed and time of descent will be same

B

Speed will be same, but time of descent will be different

C

Speed will be different, but time of descent will be same

D

Speed and time of descent both are different

Text Solution

Verified by Experts

The correct Answer is:
B
`v= sqrt((2gh)/(1+ (K^(2))/(R^(2)))), t= (1)/(sin theta) sqrt((2h)/(g) (1+ (K^(2))/(R^(2))))`
