Two points masses `m` each are kept at the two verticle of an equilateral triangle of side 'a' as shows in figure.

Find gravitational potential and magnitude of field strength at `O`.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`V = - (Gm)/(a) - (Gm)/(a) = - (2 Gm)/(a)`

`E = (Gm)/(a^(2))`
`E_(net) = sqrt(E^(2) + E^(2) + 2(E)(E) cos 60^(@)) = sqrt(3) E`
`= sqrt(3 Gm)/(a^(2))`
