Answer on Question #51297-Physics-Field Theory

Determine the electric potential energy of the system of Charges shown in figure below:

Solution

The electric potential energy of the system of Charges is

$$U = k \left(\frac {q _ {1} q _ {2}}{r _ {1 2}} + \frac {q _ {3} q _ {2}}{r _ {3 2}} + \frac {q _ {1} q _ {3}}{r _ {1 3}}\right) = 9 \cdot 1 0 ^ {9} \left(\frac {3 \cdot 5}{3} + \frac {4 \cdot 5}{4} + \frac {3 \cdot 4}{5}\right) = 1. 1 1 6 \cdot 1 0 ^ {1 1} J.$$
