Four particles of masses m, 2m, 3m and 4m are kept in sequence at the corners of a square of side a. The magnitude of gravitational force acting on a particle of mass m placed at the centre of the square will be
- \(\frac{24 m^{2} G}{d^{2}}\)
- \(\frac{6 m^{2} G}{a^{2}}\)
- \(\frac{4 \sqrt{2} G m^{2}}{a^{2}}\)
- zero
Answer
(C) 4 2 G m^ 2 a^ 2
