question 2

Multiple Choice

A satellite of 1000 kg is in a circular orbit at a height of R_E above the surface of Earth. Calculate the minimum energy required to put such a satellite into this orbit R_E = 6.38 x 10⁶ m, M_E = 5.98 x 10²⁴ kg, G = 6.67 x 10^-11 N · m²/kg²) . Assume the satellite is stationary on Earth's surface and is moving with appropriate speed on the orbit.
