#### Solution

The gravitational force of attraction between the balls is given as by

$F = \frac{G m_1 m_2}{r^2}$

$\text { Given } : m_1 = m_2 = 10 kg \text { and } r = 10 cm = 0 . 10 m$

$\therefore F = \frac{6 . 67 \times {10}^{- 11} \times 10 \times 10}{\left( 0 . 1 \right)^2}$

$\Rightarrow F = 6 . 67 \times {10}^{- 7} N$

Is there an error in this question or solution?
