Three objects - - two of mass m and one of mass m - - are located at three corners of a square of edge length ℓ. find the gravitational field g at the fourth corner due to these objects. (express your answers in terms of the edge length ℓ, the masses m and m, and the gravitational constant g). magnitude

The magnitude of the gravitational field is = GM/R^2Where:R = l, and G = gravitation constant, m = mass

The field strength of the diagonal mass is computed by GM / (l*√2) ^2

And the sum of the field magnitudes from the two neighbored masses is GM*√2/l^2.

So the total magnitude is computed by: GM / (2l^2) + GM√ (2) / l^2
