Question

Two spherical balls of mass 10 kg each are placed 10 cm apart. Find the gravitational force of attraction between them.

Answer 1

Thanks for asking the question!

ANSWER::

Mass of each ball, m = 10 kg  = M

r = 10 cm = 0.10 m

G = 6.67x10⁻¹¹ N-m²/kg²

F = GMm/r²

= (6.67x10⁻¹¹ x10x10)/(0.10)² N

= 6.67x10⁻¹¹ x10⁴ N

= 6.67x10⁻⁷ N

Hope it helps!
