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

Open in App

Solution

The gravitational force of attraction between the balls is given as by
$F = \frac{G m_{1} m_{2}}{r^{2}} Given : m_{1} = m_{2} = 10 kg and r = 10 cm = 0.10 m$
$∴ F = \frac{6.67 \times 10^{- 11} \times 10 \times 10}{{(0.1)}^{2}} \Rightarrow F = 6.67 \times 10^{- 7} N$
