Electric Potential Difference
5.14) Four equal point charges of
charge q=+5µC are located at the
corners of a 30cm by 40cm
rectangle. Calculate the electric
potential energy stored in this
charge configuration.
5.15) Two point charges, Q 1 =+5nC
and Q 2 =-3nC, are separated by
35cm. (a) What is the potential
energy of the pair? What is the
significance of the algebraic sign of
your answer? (b) What is the
electric potential at a point midway
between the charges?
