Answer:
3.36m or 1680 N
Explanation:
Given:
Mass of the satellite =m
Mass of the moon Ganymede, M = 1.48 × 10²³ kg
Radius of Ganymede, R = 2631 km
Distance of satellite above the surface of the moon, d = 300 km
According to Universal Gravitational law:
where, G is the gravitational constant, M and m are mass of the objects and (R+d) is the distance between the centers of the objects.
Substitute the values:
If we consider mass of a satellite to be about 500 kg, the gravitational force between the moon and the satellite would be:
Answer:
22 mins and 30 seconds
Explanation:
2m in 1 min so:
45m in x mins Cross multiply
2x = 45
x = 45/2
x=22.5
