Two identical small insulated conducting spheres

Reference no: EM13561685

Two identical small insulated conducting spheres, whose centers are 18.9 cm apart, carry charges Q1=-100microC and Q2=-200microC, respectively. The spheres are kept insulated, but are then brought into mutual contact and then returned to their original positions. How much does the potential energy of the two spheres change from the initial to the final configuration (i.e., PEf-PEi).
