Question
The period of oscillation of simple pendulum of length L suspended from the roof of the vehicle which moves without friction, down an inclined plane of inclination α, is given by
Options
A.
B.
C.
D.
Solution
Free body diagram og bob of the pendulum with respect to the accelerating frame of refrence is as follows
∴ Net force on the bob is Fnet = mg cos α
or Net acceleration of the bob is geff = g cos α
T =
or T =
