Question

Quizplus · Accepted Answer

The electrical potential at the point midway between the two charges can be calculated using the formula:

V = k(q1/r1 + q2/r2)

where k is the Coulomb constant, q1 and q2 are the charges, r1 and r2 are the distances between the point and each charge.

Since the point is midway between the two charges, r1 = r2 = 0.05 m.

Substituting the values, we get:

V = (8.99 x 10^9 Nm^2/C^2)(3.4 x 10^-6 C/0.05 m + 6.6 x 10^-6 C/0.05 m)

V = 0.90 x 10^6 V = +0.90 x 10^16 V

So, the electrical potential at the point midway between the two charges is +0.90 x 10^16 V, which is option C.
