Question

two spheres of mass 20kg and 10kg are 20cm apart calculate the force between them​

Answer 1

Explanation:

Masses of the spheres are:

m₁ = 10kg

m₂ = 5kg

distance, r = 5m

Force of attraction between them is due to gravitational attraction.

F=\frac{Gm_1m_2}{r^2} = \frac{6.67 \times 10^{-11} \times 10 \times 5}{5^2}\ N=1.334 \times 10^{-10}N

The force of attraction between the spheres is 1.334 × 10⁻¹° N

Answer 2

Answer:

a sphere of mass 20kg is attracted by another sphere of mass 10kg when their centres are 20cm apart , with a force of 3.3×10^-7N
