Question

derive an expression for electrostatic potential due to system of changes 12th ​

Answer 1

Answer:

hi plz mark me as brilliant

Explanation:

Using calculus to find the work needed to move a test charge q from a large distance away to a distance of r from a point charge Q, and noting the connection between work and potential (W = −qΔV), it can be shown that the electric potential V of a point charge is V=kQr V = k Q r
