Question

Two balls have their centers 2.2 m apart. One ball has a mass of 4.5 kg. The other has a mass of 9.5 kg. What is the gravitational force between them?

Answer 1

Answer:

Explanation:

Given

Distance between two balls is $d=2.2\ m$

mass of first ball $m_1=4.5\ kg$

mass of second ball $m_2=9.5\ kg$

Gravitational force between two forces is given by

$F=\dfrac{Gm_1m_2}{d^2}$

Substituting values

where G=gravitational constant

$F=\dfrac{6.674\times 10^{-11}\times 4.5\times 9.5}{(2.2)^2}$

$F=58.94\times 10^{-11}\ N$
