Phys 202A Homework 7 Solutions 7. Since point P lies directly
... 7. Since point P lies directly between the two identical +5.0q charges, the field due to one of those charges is equal in magnitude and opposite in direction to the field due to the other charge. Their sum is zero. Note that the +3.0q charge and the –12q charge produce electric fields at P in opposi ...
