For a particle to leave from the earth's field, it should be projected with a minimum velocity. Find the period of a simple pendulum, if this experiment is performed inside a satellite?

For a particle to leave from the earth's field, it should be projected with a minimum velocity. Name the velocity.

For a particle to leave from earth's gravitation field it should be projected with a minimum velocity. Derive an expression for this velocity.

For a particle to leave from earth's gravitation field it should be projected with a minimum velocity. What is the magnitude of this velocity when this particle is projected from another planet whose mass and radius is twice that of the earth?

For a particle to leave from the earth's field, it should be projected with a minimum velocity. An elephant and an ant are to be projected from earth into space. Whether the velocities required for doing so are the same or different? Justify your answer.

For a particle to overcome the gravitational pull of the Earth, it is projected with a minimum velocity. A ball bounces more on the surface of the moon than on the earth. Explain why?

A stone is thrown upward from a moving train. a)Name the path followed by the stone. b)A particle is projected with a velocity u in the direction making an angle theta with the horizontal.Find: (1)Time of flight,(2)Maximum height. c)A man can jump on moon six times as high as on earth.Why?

A simple pendulum has a bob of mass m is suspended from the ceiling of a lift which is lying at the ground floor of a multistoried building. Find the period of oscillation of pendulum when the lift is stationary.
