Four point masses each of mass 'm' are placed on the corner of square of side 'a' Calculate magnitude of gravitational force experienced each particle
.

Explanation

`F_(r) =` resultant force on each particle `=2F cos 45^(@) + F_(1)`
`=(2G.m^(2))/(a^(2)).(1)/(sqrt2)+(Gm^(2))/((sqrt(2a))2)= (G.m^(2))/(2a^(2))(2sqrt2+1)`
