Question

The planet Mars has two moons, if one of them has a period 7 hours, 30 minutes and an orbital radius of 9 . 0 × 10 3 km . Find the mass of Mars. Given 4 π 2 G = 6 × 10 11 N - 1 m - 2 kg 2, 5 . 96 × 10 19 kg, 3 . 25 × 10 21 kg, 7 . 02 × 10 25 kg, 6 . 00 × 10 23 kg

MARKS App · Accepted Answer

Option D is correct. T 2 = 4 π 2 G M · r 3 M = 4 π 2 G · r 3 T 2 By putting values M = 6 × 10 23
