Two electrons are placed at two corners of an equilateraltriangle whose sides are 2.0 nm long. ( 1 nm =10-9m )
a. Calculate the magnitude of the electric potential (referenced to V = 0 at infinity) presentat the empty corner of the triangle due to the two electrons.
b. How much work is required toplace a third electron at the vacant corner of the triangle?
c. After the third electron has been placed at the vacant third corner of the triangle, calculate the total electrical potential energy of the system of three electrons
