Gravitation · Potential energy, potential, escape, satellites

Initially a satellite of 100 kg is in a circular orbit of radius 1.5RE1.5R_E. This satellite can be moved to a circular orbit of radius 3RE3R_E by supplying α×106\alpha\times10^{6} J of energy. The value of α\alpha is . (Take Radius of Earth RE=6×106R_E = 6\times10^{6} m and g=10 m/s2g = 10\ \mathrm{m/s^2})
