4 point charges each have charge q = 4 nC, are located at r= 3, 4, 5, 6 m respectively. If r represents the distance from the origin, then total potential at the origin is: Select one:

Expert Solution

Answer:-

Given that,

Charge of the point charges, = =

We know that the formula for finding electric potential at a distance from a point charge is,

Where, is the permittivity of the free space. Numerical value of is

By using the informations given in the problem, we can draw a rough figure as shown below,

Therefore,

where, are the successive distances to the point charges from the origin O.

Substituting the values, we get,

Hence, Electric potential at the origin due to the four equal point charge is 34.2 V
