Question

Electric charges The drawings show three charges that have the same magnitude, but different signs. In all cases the distance d between the charges is the same.

(a) For drawing (a), which answer below shows correctly the force vector F 21 exerted on charge 2 by charge 1 and the force vector F 23 exerted on charge 2 by charge 3?

(b) For drawing (b), which answer below shows correctly the force vector F 21 exerted on charge 2 by charge 1 and the force vector F 23 exerted on charge 2 by charge 3?

(c) For drawing (c), which answer below shows the force vector F 21 exerted on charge 2 by charge 1 and the force vector F 23 exerted on charge 2 by charge 3?

(d) For the three cases shown in the drawing, rank the magnitudes of the net electrical force exerted on charge 2, largest first.

(c), (a), and (b)

(c), (b), and (a)

(a), (b), and (c)

(a), (c), and (b)

The magnitude of the charges is |q| = 8.3

Explanation / Answer

a)2 b)2 c)1 d)a>c>b e)F=k * (q^2) / (r^2) f)force = 2F = 113.867 kN g)force = F*sqrt(2) = 80.52 kN
