Particles P and Q areinitially at rest 1.0 m apart. P has a mass of0.10 kg and Q a mass of 0.30kg. P and Q attract eachother with a constant force of 10–2 N. No external forces act on the system.
a) Describe the motion of the center of mass.
b) At what distance from P’soriginal position do the particles collide? Explain.
