Question 87

Two communication satellites, K and L, orbit at different distances from a planet. Satellite L has a mass 1.5 times the mass of satellite K.

SatelliteGravitational field strength in N kg−1\text{N kg}^{-1}N kg−1
K2.4
L0.60

The weight of satellite K is 7200 N.

Calculate the weight of satellite L and the ratio of the weight of satellite K to the weight of satellite L.

Give the ratio in its simplest whole-number form.
