Question

Two satellites in space with a mass of 2000kg, are 1500m apart from each other. What is the force gravity between them?

Answer 1

F = 1.185 x 10⁻¹⁰ N

Step-by-step explanation:

The force of gravitation between two objects is given by Newton's Law of Gravitation. According to this law:

`F = (Gm_(1)m_(2))/(r^(2))\\`

where,

F = Gravitational Force between satellites = ?

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ Nm²/kg²

m₁ = m₂ = mass of each satellite = 2000 kg

r = distance between both satellites = 1500 m

Therefore,

`F = ((6.67\ x\ 10^(-11)\ Nm^(2)/kg^(2))(2000\ kg)(2000\ kg))/((1500\ m)^(2))\\\\`

F = 1.185 x 10⁻¹⁰ N
