Questions
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 , is given by
detailed solution
Correct option is A
See the following force diagram.Vehicle is moving down the frictionless inclined surface so, it's acceleration is gsinθ . Since vehicle is accelerating, a pseudo force m(gsinθ) will act on bob of pendulum which cancel the sinθ component of weight of the bob.Hence net force on the bob is Fnet =mgcosθ or net acceleration of the bob is geff=gcosθ∴ Time period T=2πLgeff=2πLgcosθTalk to our academic expert!
