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 seconds pendulum is suspended form the roof of a lift. If the lift is moving up with an acceleration 9.8 m//s^(2) , its time period is

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.

A simple pendulum is suspended from the roof of a train. If the train is moving with an acceleration 49 cm//s^(2) . Then the angle of inclination of the string about the vertical will be

A pendulum is suspended from the roof of a rall road car. When the car is moving on a circular track the pandulum inclines:

A seconds pendulum is suspended from the ceiling of a trolley moving horizontally with an acceleration of 4 m//s^(2) . Its period of oscillation is

A simple pendulum suspended from the ceiling of a trans has a time period T when the train is at rest. If the train is accelerating uniformly at a then its time period

A car is moving in a circular horizontal track of radius 10 m with a constant speed of 10 m/s. A plumb bob is suspended from the roof of the car by a light rigid rod. The angle made by the rod with the vertical is (g = 10 m//s^(2))

A train is moving along a straight line with a constant acceleration a. A body standing in the train throws a ball forward with a speed of 10ms^(-1) , at an angle of 60^(@) to the horizontal . The body has to move forward by 1.15 m inside the train to cathc the ball back to the initial height. the acceleration of the train. in ms^(-2) , is:
