Question

For the charge distribution provided, indicate the region (a to e) along the horizontal axis where a point exists at which the net electric field is zero?

1) a
2) b
3) c
4) d
5) e

Answer 1

For the charge distribution provided, the region (a to e) along the horizontal axis where a point exists at which the net electric field is zero is 3. C.

What is the region?

In this region C, we can see that the two positive charges are equidistant from each other. This implies that they share the same strength and magnitude although they move in opposite directions. In summary, the net charges accumulated by these points would equal to zero.

So, the conclusion is that for the charge distribution provided, the region along the horizontal axis where a point exists at which the net electric field is zero is region C.
