Question

In the figure particles with charges *q*_{1} = +6*e* and *q*_{2} = -14*e* are fixed in place with a separation of *d* = 18.6 cm. With *V* = 0 at infinity, what are the finite **(a)** positive and **(b)** negative values of *x* at which the net electric potential on the *x* axis is zero?

Step 1

Given,

Step 2

Potential is scalar quantity, the electric potential due to the system of charge can be found by adding potential due to individual charges,

Step 3

Charge 1 at origin and charge 2 is at distance d on the x-axis.

Assume a point P on the x-axis at...
