A train is moving along a horizontal track . A pendulum suspended from the roof makes an angle of `4^(@)` with the vertical . If `g = 10 m//s^(2)` , what is the acceleration of the train ?

A car moving on a level rosd. A pendulum suspended from the ceiling makes an angle of 10^(@) with the vertical. Find the acceleration of the car. Take g=10ms^(-2) .

A simple pendulum is suspended from the roof of a lift. What will be its time period when the lift moves downwards with an acceleration a

A plumb bob is hung from the ceiling of a train compartment. If the train moves with an acceleration a along a straight horizontal track, the stirng suporting the bob makes an angle tan^1 (a/g) with the normkal to the ceiling. Suppose the train moves on an inclined straight track with uniform moves on aninclined straight track with uniform velocity. If the angle of incline is tan^-1(a/g) , the string again makes the same angle with the normal to the ceiling. Can a person sitting inside the compartment tell by lookign at the plumb line whether the train is accelerated on a horizontal straight track or it is going on an incline? If yes, how? If no, suggest a method to do so.
