# Problem: Two point charges are separated by 25.0 cm (see the figure (Figure 1) ). Assume that q1 = 6.05 nC and q2 = 11.5 nC.A. Find the magnitude of the net electric field these charges produce at point A.B. Find the magnitude of the net electric field these charges produce at point B.C. What would be the magnitude of the electric force this combination of charges would produce on a proton at A?

###### FREE Expert Solution

In this problem, we're going to use the equation for the electric field:

$\overline{){\mathbf{E}}{\mathbf{=}}\frac{\mathbf{k}\mathbf{q}}{{\mathbf{r}}^{\mathbf{2}}}}$, where k is Coulomb's constant, q is change, and r is the distance between the charge and the point where the electric field is produced.

The electric force is given by:

$\overline{){\mathbf{F}}{\mathbf{=}}{\mathbf{q}}{\mathbf{E}}}$.

A.

Electric field lines are directed toward negative point charges and away from positive charges.

At point A, the electric field due to q1 will be directed on the negative x-axis while the electric field due to q2 will be on the positive x-axis.
