(1) Data : m1 = 60 kg, m2 = 7.36 × 1022 kg,
R = 1.74 × 106 m, F = ?
= 97.29 N
On the moon’s surface, the gravitational force on the man due to the moon = 97.29 N.
(2) Data : m1 = 60 kg, m2 = 6.4 × 1023 kg,
R = 3.395 × 106m, F = ?
= 222.2 N
On the surface of Mars, the gravitational force on the man due to Mars = 222.2 N.
(3) Data : m1 = 60 kg, m2 = 1.9 × 1027 kg,
R = 7.15 × 107 m, F = ?
= 1487 N
On the surface of Jupiter, the gravitational force on the man due to Jupiter = 1487 N.
Thus, the forces on the man are not the same because the ratio (M/R2) is not the same in the case of the moon, Mars, and Jupiter.
