Infinite number of masses, each of mass m, are placed along a straight line at distances of r, 2r, 4r, 8r, etc. from a reference point O. The gravitational field intensity at point O will be
- \(\frac{5 G m}{4 r^{2}}\)
- \(\frac{4 G m}{3 r^{2}}\)
- \(\frac{3 G m}{2 r^{2}}\)
- \(\frac{2 G m}{r^{2}}\)
Answer
(B) 4 G m 3 r^ 2
