Problem

Consider two separate pairs of point masses kept in air as described below: Pair I:

m_1 = 2.0\,\text{kg}

and

m_2 = 2.0\,\text{kg}

separated by

0.50\,\text{m}

. Pair II:

m_3 = 0.50\,\text{kg}

and

m_4 = 3.0\,\text{kg}

separated by

0.25\,\text{m}

. (i) Calculate the gravitational force between the masses in each pair. (ii) Which pair experiences the larger gravitational force? State the factor by which it is larger.
