Two small metal spheres with masses 2 gram and 4 gram are tied together by a 4.6 centimeter long mass less string and are at rest on a frictionless surface. Each is charged to +1.7 μC.
A) Compute what is the energy of this system?
E0= _____________ J
B) Compute what is the tension in the string?
T= ______________ N
C) The string is cut. Obtain the speed of each sphere when they are far apart? Hint: There are two conserved quantities. Make use of both.
