Question

The figure to the right shows two positive point charges each with charge +Q and equidistant from the origin. At what point or points within the dashed curve is the electric potential zero?

(a) The potential is only zero at the origin.

(b) The potential is zero at all points on the line connecting the charges.

(c) The potential is zero at all points along the x axis.

(d) The potential is zero at all points along the y axis.

(e) The potential is non-zero at all points.

Online Homework Problem 9.8 [3 pt(s)] The figure to the right shows two positive point charges each with charge +Qr and equidistant from the origin. At what point or points within the dashed curve is the electric potential zero? Select One of the Following: (a) The potential is only zero at the origin. (b) The potential is zero at all points on the line connecting the te x charges. (c) The potential is zero at all points along the z axis. (d) The potential is zero at all points along the y axis. (e) The potential is non-zero at all points.

Explanation / Answer

both charges are +ve charges

electric potential is a scalar quantity

so at all points the potential will be non zero . OPTION (e)
