Question: Two charged objects 1 and 2 are held a distance (r) apart. Object 1 has mass (m) and charge (+2 q), and object 2 has

Two charged objects 1 and 2 are held a distance $r$ apart. Object 1 has mass $m$ and charge $+2 q$, and object 2 has mass $2 m$ and charge $+q$. The objects are released from rest. Assume that the only force exerted on either object is the electric force exerted by the other object.

(a) When the objects are in motion, what is the ratio of their kinetic energies $K_{2} / K_{1}$ ? When the objects are a distance $4 r$ apart, what is the speed of $(b)$ object 1 and (c) object 2 ? When the objects are very far apart, what is the speed of (d) object 1 and (e) object 2?
