Pseudo Force & Non-Inertial FramesHardQuestion 5432

Question

A box is in an accelerating truck (acceleration a). The angle of tilt of a pendulum inside the truck is:
  1. A
    tan⁻¹(g/a)
  2. B
    tan⁻¹(a/g)
    Correct
  3. C
    sin⁻¹(a/g)
  4. D
    cos⁻¹(a/g)

Correct answer

tan⁻¹(a/g)

Explanation

In the non-inertial frame, the pendulum experiences pseudo force ma horizontally and mg vertically. tanθ = a/g, so θ = tan⁻¹(a/g).
