Asked by Arianne
Two small metal spheres with masses 2.0 g and 4.0 g are tied together by a 5.0 cm long massless
string and are at rest on a frictionless surface. Each is charged to +2.0 ìC.
(b) What is the tension in the string?
(c) The string is cut. What is the speed of each sphere when they are far apart?

tension= force repulsion= kQ1*Q2/distance^2
when cut, then T=ma or a= tension/mass
when cut, then T=ma or a= tension/mass
