Question

a simple pendulum is oscillating in a vertical plane. If resultant acceleration of bob of mass m at a point A is in horizontal direction,find the tangential force​

Answer 1

Answer:

1. the net result t= 2π√l/2G

Answer 2

The tangential force is ma.

Explanation:

Given:

The mass of the oscillating body is m and the horizontal tangential acceleration of the body at lowest point is a.

We know that horizontal acceleration occurs at the lowest point and it is the maximum acceleration in whole oscillation. The kinetic energy is maximum.

We know that,

                                Tangential acceleration = m x a

                                                             = ma
