asked 11/02/21Two spheres m1 = 9.00 kg and m2 = 2.50 kg are located along the x axis at (−5.10, 0) m and (0, 0) m, respectively, as shown in the diagram below.
What is the absolute value of the work that has to be done in bringing a mass of 1.00 kg from infinity to P, which is at location (0, 2.55) m?

GPE = Gm1*m3/r13+ Gm2*m3/r23
Plug in G, m1, m2, m3, r13, r23
m1= 9kg, m2= 2.5 kg, m3 = 1kg
r23 = 2.557 m, Find r13 using Pythagorean Theorem
