Three uniform spheres are fixed at the positions shown in the figure below. (m1 = 1.0 kg, m2 = 2.0 kg, and d = 0.60 m.)

(See attached picture)

(a) What are the magnitude and direction of the force on a 0.0250-kg particle placed at P?

(b)If the spheres are in deep outer space and a 0.0250-kg particle is released from rest 300 m from the origin along a line 45° below the -x-axis, what will the particle's speed be when it reaches the origin?

2. Relevant equations

I used some good old trig and GMm/r^2 to get the answers to a, which were 1.11875e-11 N and 45 degrees.

for b I really have no idea where to go with it...
