If gravitational attraction between two points masses be given by F=G rn/m1m2 . Then the period of a satellite in a circular orbit will be proportional to If gravitational attraction between two points masses be given by F=G rn/m1m2 . Then the period of a satellite in a circular orbit will be proportional to September [...]

Consider the two identical particles shown in the given figure. They are released from rest and may move towards each other influence of mutual gravitational force. The velocity of centre of mass of the two particle system: The distance of two planets from the sun are 10^13 and 10^12 m respectively. The ratio of the [...]

Suppose the gravitational attraction varies inversely as the distance from the earth. The orbital velocity of a satellite in such a case varies as nth power of distance where n is equal to Suppose the gravitational attraction varies inversely as the distance from the earth. The orbital velocity of a satellite in such a case [...]

A particle is projected vertically upward from the surface of earth (radius R ) with a kinetic energy equal to half of the minimum value needed for it to escape. The height to which it rises above the surface of earth is The distance of two planets from the sun are 10^13 and 10^12 m [...]

A simple pendulum has a time period T1 when on the earth’s surface and T2 when taken to a height R above the earth’s surface, where R is the radius of the earth. The value of T1/T2 is: A simple pendulum has a time period T1 when on the earth's surface and T2 when taken [...]

A body of mass m is kept at a small height h above the ground. If the radius of the earth is R and its mass is M, the potential energy of the body and earth system (with h= ∞ being the reference position) is A body of mass m is kept at a small [...]

A satellite moves round the earth in a circular orbit of radius R making one revolution per day. A second satellite moving in a circular orbit, moves round the earth one in 8 days. The radius of the orbit of the second satellite is A satellite moves round the earth in a circular orbit of [...]
