A very large number of particles of same mass m are kept at horizontal distances of 1m, 2m, 4m, 8m and so on from (0,0) point. The total gravitational potential at this point (0, 0) is:
Text Solution
Verified by ExpertsThe correct answer is:
D
v = v 1 + v 2 + v 3 + v 4 + ......
= –

= – Gm 
→ G.P. of infinite series
= – m 
v = – Gm = – 2Gm
