Question

derive the formula for the electric potetinal energy of system of three charges.​

Answer 1

Answer:

To calculate the electrostatic potential energy of a system of charges, we find the total work done, by the external agent, in assembling those charges. Since electrostatic fields are conservative, the work done is path-independent.

Answer 2

Answer:

we get the electric potential at the centre as zero. Therefore we have the electric field at the centre of the triangle as non – zero and the electric potential at the centre of the triangle as zero.
