Problem

A point mass

m

is located at the origin. Two other fixed masses are positioned at

(0,\,d)

with mass

4m

and at

(d,\,0)

with mass

3m

. What is the magnitude of the net gravitational force on the mass at the origin in terms of

G

m

, and

d

? a)

\dfrac{7Gm^{2}}{d^{2}}

\dfrac{5Gm^{2}}{d^{2}}

\dfrac{7Gm^{2}}{2d^{2}}

\dfrac{25Gm^{2}}{d^{2}}
