A skylab of mass `m` kg is first launched from the surface of the earth in a circular orbit of radius `2R` (from the centre of the earth) and then it is shifted from this circular orbit to another circular orbit of radius `3R`. The minimum energy required to place the lab in the first orbit and to shift the lab from first orbit to the second orbit are

A sky lab of mass 2 xx 10^(3)kg is first launched from the surface of earth in a circular orbit of radius 2R and them it is shifted from this circular orbit to another circular orbit of radius 3R . Calculate the energy required (a) to place the lab in the first orbit, (b) to shift the lab from first orbit to the second orbit. (R = 6400 km , g = 10 m//s^(2))
