A simple pendulum is suspended from the roof of a railway carriage. What angle does the string make with the vertical if the carriage travels at a constant speed of 72 km/h around a circular track of radius 100m? Take `g=9.8 m//s^2`.

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 suspended from the roof of a railway carriage travelling at a speed v mis round a curve of radius 'a' metres makes n oscillations per second. If the same pendulum makes n_1 oscillations per second when the carriage is stationary, what is the value of v_2 ?

At what angle should a road be banked so that the vehicle may take a bend of radius 10 m travelling with a speed of 10 m//s ?

A simple pendulum of length 1 m the bob performs circular motion in horizontal plane if its string making an angle 60 ^(@) with the verticle , then the period of rotation of the bob will be (g=10 m//s^(2)

What is the velocity of the bob of a simple pendulum at its mean position, if it is able to rise to vertical height of 10 cm (take g=9.8m//s^(2) )

A simple pendulum of length 1 m is freely suspended from the ceiling of an elevator. The time period of small oscillations as the elevator moves up with an acceleration of 2m//s^2 is (use g=10 m//s^2 )

If the density of the earth is doubled keeping its radius constant then acceleration due to gravity will be (g=9.8 m//s^(2))

If the density of the earth is tripled keeping its radius constant, then acceleration due to gravity will be (g=9.8 m/s^2)
