Answer:
Answer a) Force on A equal to force on B
Answer a) The electric field points to the left in the location A
Explanation:
12)
Recall that the magnitude of the electrostatic force is given by:
[tex]F=k\frac{q*Q}{d^2}[/tex]
therefore in magnitude it is the same for charge q than for charge Q.
(Answer a for the first problem - 12)
13)
Recall that the electric filed points outwards for a positive charge, therefore at the location of charge q, the field must be pointing towards the left.
