Three masses \( 200 \,\text{kg} \), \( 300 \,\text{kg} \) and \( 400 \,\text{kg} \) are placed at the vertices of an equilateral triangle with sides \( 20 \,\text{m} \). They are rearranged on the vertices of a bigger triangle of side \( 25 \,\text{m} \) and with the same centre. The work done in this process ________ \( \text{J} \).
\( \left(\text{Gravitational constant } G = 6.7 \times 10^{-11} \, \text{N m}^{2}/\text{kg}^{2}\right) \)
