Just like electric fields, the potential at a point in space is the sum of the potential due to all the charges. However, unlike electric fields, there is no vector stuff to worry about! Potential is a scalar. So you just compute this scalar numberV=kqrfor each charge, and add them up! P-Q2 IS 0.30M
Q1 - Q2 IS 0.60M To practice this idea, consider the following arrangement of charges:
In the figure above q1=4.5nC,q2=-2.3nC, and q3=3.6nC. What is the electric potential at point P ? unit.
