the hubble telescope has a mass of 1.5 x 10^4 kg and its orbiting the earth 596 km above the ground surface.the earths radius is 6.38 x 10^3km. CAlculate
a)the force of gravitation on the telescope due to the earth's pull.
given: G=6.67 x 10^-11Nm/kg and the mass of earth is 5.98 x 10^24.
b)the telescope's orbital speed and the time it takes to complete one revolution.(consider the centripetal force is supplied by the force of gravitation between the telescope and the earth).
