A simple pendulum is set up in a trolley which moves to the right with an acceleration a on a horizontal plane. Then the thread of the pendulum in the mean position makes an angle θ with the vertical

a
tan−1ag in the forward direction
b
tan−1ag in the backward direction
c
tan−1ga in the backward direction
d
tan−1ga in the forward direction

detailed solution

Correct option is B

In accelerated frame of reference, a fictitious force (pseudo force) ma acts on the bob of pendulum as shown in figure.Hence, tanθ=mamg=ag⇒θ=tan−1ag in the backward direction.
