A simple pendulum with a bob of mass m oscillates from A to C and back to 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………..

A simple pendulum with a bob of mass m oscillates from A to C and back

1.	A simple pendulum with a bob of mass m oscillates from A to C and back to 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………..
Answer» `mgH` `SQRT(2gH)` `2gH` zero Solution :`TRIANGLE PE = triangle KE` `mgH= (1)/(2) mv^(2) IMPLIES v= sqrt(2gH)`
