Gravitation Tes...

An artificial satellite is revolving round the earth in a circular orbit. its velocity is half the escape velocity. Its height from the earth surface is = ............... km

The escape velocity of a planet having mass 6 times and radius 2 times as that of earth is..........

There are two planets, the ratio of radius of two planets is k but the acceleration due to gravity of both planets are g what will be the ratio of their escape velocity.

The escape velocity of a body on the surface of the earth is 11.2 km/sec. If the mass of the earth is increases to twice its present value and the radius of the earth becomes half, the escape velocity becomes = ………..kms^–1

3 particle each of mass m are kept at vertices of an equilateral triangle of side L. The gravitational field at centre due to these particles is ................

Escape velocity on the surface of earth is 11.2 kms^-1 Escape velocity from a planet whose masses the same as that of earth and radius 1/4 that of earth is = ....... kms^–1

The velocity with which a projectile must be fired so that it escapes earth’s gravitational does not depend on ..................

The escape velocity for a body projected vertically upwards from the surface of earth is 11kms^–1 If the body is projected at an angle of 45^o with the vertical, the escape velocity will be ............kms^–1

The acceleration due to gravity on a planet is same as that on earth and its radius is four times that of earth. What will be the value of escape velocity on that planet if it is Ve on the earth
