Two bodies of masses M1 and M2 are initially at rrest a distance R apart. They then move directly towards one another under the influence of their mutual gravitational attraction. What is the ratio of distance moved by M1 to the distance moved by M2 ?

The eccectricity of the earth&apos;s orbit is 0.0167. The ratio of its maximum speed in its orbit to its minimum speed is

The diameters of two planets are in the ratio 4:1 and their mean densities are in the ratio of 1:2. the acceleration due to gravity on the two planets will be in the ratio

If g is the acceleration due to gravity on the earth&apos;s surface, the gain in potential energy of an object of mass m raised from the surface of earth to a hieght equal to the radius R of the earth is

There are two bodies of masses 1000kg and 100000kg separated by a distance of 1km. At what distance from the smaller body, the intensity of gravitational potential due to smaller body is 10 times the gravitational potential due to larger one

A boy can jump 2 m on the surface of the earth. how high can he jump on the surface of the moon? (assume the acceleration due to gravity on moon&apos;s surface is 1/5 that on the surface of earth)

The mass of the moon is 1/81, that of the earth and its radius is 1/4 that of the earth. If the escape velocity from the earth&apos;s surface is 11.2 km/s, the value of escape velocity from the surface of the moon will be

If an orbiting satellite is suddenly stopped

Two astronauts have deserted their spaceship in a region of space far from the gravitational attraction of any other body. Each has a mass of 100 kg and they are 100 m apart. They are initially at rest relative to one another. How long will it be before the gravitational attraction brings them 1 cm closer together?

A satellite is launched into a circular orbit of radius R around the earth. A second satellite is launched into an orbit of radius 1.01 R. The time period of the second satellite is larger than that of the first one by approximately

A real of massless thread unrolls itself falling down under gravity. The acceleration of its fall is

A satellite is moving around the sun. In order to make it move to infinity, its speed must be increased by,
