Question

The period of oscillation of a simple pendulum of length L suspended from the roof of a vehicle which moves without friction down an inclined plane of inclination α is given by, 2 π L g cos ⁡ α, 2 π L g sin ⁡ α, 2 π L g, 2 π L g tan ⁡ α

MARKS App · Accepted Answer

When vehicle is accelerated F pseudo will act on pendulum which will balance the force along the incline. F P = m g sin ⁡ α Therefore, g eff = gcos ⁡ α . ∴ T = 2 π L g cos ⁡ α
