Question

11.) A charge 6 uC is placed at the origin
and another charge. -5 uC is placed on
the y axis at a position A (0, 6.0) m.


a) Calculate the total electric potential
at the point P whose coordinates are
(8.0, 0) m
b) Calculate the work done to bring
a proton from infinity to the point
P ? What is the significance of the
negative sign?
