Questions
A simple pendulum with a bob of mass 'm' oscillates from A to C and back to A such that PB is H. If the acceleration due to gravity is ' g ', then the velocity of the bob as it passes through B is
detailed solution
Correct option is D
At B, the velocity is maximum. Taking vertical downward motion of body from A to B, we have, u=0, a=g, s=H and v= ? As v2=u2+2as; so v2=0+2 gH or v=2 gHTalk to our academic expert!
