What is the value of escape velocity of a body lying on the surface of earth?
"The value of the escape velocity v_e for a stationary body on the surface of a planet is directly proportional to the mass and the radius of the planet”. Is this statement true? If not, correct it and write it.
What is the value of escape velocity of a body lying on the surface of moon ?
A particle is projected vertically upwards the surface of the earth (radius R_(e)) with a speed equal to one fourth of escape velocity what is the maximum height attained by it from the surface of the earth?
Write the expression of gravitational potential energy and gravitational potential at the surface of earth .
Derive the equation of g at depth d below the surface of earth.
Obtain an expression of acceleration produced by gravity of earth. OR Obtain general equation of gravitation force at distance r from the centre of earth and derive the equation of acceleration due to gravity on the surface of earth.
The escape velocity for a body projected vertically upwards from the surface of earth is 11 km/s. If the body is projected at an angle of 45^(@) with the vertical, the escape velocity will be
A particle is thrown with escape velocity v_(e) from the surface of earth. Calculate its velocity at height 3 R :-
If the radius of the earth becomes half of its present value but its density remains unchanged then find the weight of body on the surface of earth.
