Question
Three equal 1.40-C point charges are placed at the corners of an equilateral triangle with sides 0.700 m long. What is the potential energy of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.) Express your answer with the appropriate units. U =

Explanation / Answer
potential energy of the system
U = 3 k * q1 * q2 / r
U = 3 * 9 * 109 * ( 1.40 * 10-6 )2 / 0.700
potential energy U = 0.0756 J
