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 [...]
