Physics Gravitation Level: Misc Level

Three masses are located are follows; a 3.0-kg mass is at the origin, a 4.5-kg mass at (0.0 m, 4.0 m), and a 2.5-kg mass at (3.0 m,0.0 m). What is the gravitational energy of the system of masses? G=6.67X10 to power (-11) N x m squared.

a. -3.8x10 to power of (-10) J

b.-3.9x10 to powerof (-10)J

c.-54x10 to power of (-10)J

d.-3.2x10 to power of (-10)J
