What is the electric potential at the point indicated a dot in FIGURE EX25.31?

The value of electric potential of the dot point of the figure25.31 is

See the step by step solution

Step by Step Solution

Step 1: Theory electric potential 

The electric potential equation of a dot points

where the q is the charge points, r is the distance and permittivity free space

For the multiple Points

From the given triangle, all distances from O to other points A, B, C are equal.

Due to these facts,

Step 2: Value Calculation 

Now, the length of the bc is equal to

On the basis of the right-angle triangle

the length of

The Value of the Electric Potential of the dot point is

Step 1: Theory electric potential 

The electric potential equation of a dot points

where the q is the charge points, r is the distance and permittivity free space

For the multiple Points

From the given triangle, all distances from O to other points A, B, C are equal.
