The acceleration due to gravity on the planet A is 9 times the acceleration due to gravity on planet B. A man jumps to a height of 2 m on the surface of A. What is the height of jump by the same person on the planet B?
(2) 18 m
The man takes off with the same speed u on both planets.
⇒ Maximum height h = u22g
∴ h 1g
⇒ hBhA = gAgB = 9
⇒ hB = 9 2 = 18 m
Answer: (2)
A body of mass m is placed on earth's surface which is taken from earth surface to a height of h = 3R, then change in gravitational potential energy is
With what velocity should a particle be projected so that its height becomes equal to radius of earth?
For a planet having mass equal to mass of the earth but radius is one fourth of radius of the earth. Then escape velocity for this planet will be
A body of weight 72 N moves from the surface of earth at a height half of the radius of earth, then gravitational force exerted on it will be
