23M.1A.HL.TZ1.30

Two isolated point masses, P of mass m and Q of mass 2m, are separated by a distance 3d. X is a point a distance d from P and 2d from Q.

What is the net gravitational field strength at X and the net gravitational potential at X?

	Net gravitational field strength at X	Net gravitational potential at X
A.	$\frac{G m}{d^{2}}$	0
B.	$\frac{G m}{d^{2}}$	$- \frac{G m}{d}$
C.	$\frac{G m}{2 d^{2}}$	0
D.	$\frac{G m}{2 d^{2}}$	$- \frac{2 G m}{d}$
