Question

A simple pendulum is suspended from the roof of a trolley which moves in a horizontal direction with an acceleration a,then the time period is given by T=2pai root l/g,where g is equal to ​

Answer 1

Answer:

The pendulum is suspended from the roof of a trolley which is moving in horizontal direction with accelerationa

Hence the force acting will be

F=mai−mgj

Let θ angle between the horizontal and vertical then

tanθ=

mg

ma

Then the value of g' pai g²+a²
