The time period of a geostationary satellite at a height 36000 km is 24 hrs. A spy satellite orbits very close to earth surface (R=6400 km). What will be its time period

A planet in a distant solar system is 10 times more massive than the earth and its radius is 10 times smaller. Given that the escape velocity from the earth is 11 km s^-1, the escape velocity from the surface of the planet would be

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
