Question

A charge of 8.473 nC is uniformly distributed along the x-axis from −1 m to 1 m . What is the electric potential (relative to zero at infinity) of the point at 5 m on the x-axis? The value of the Coulomb constant is 8.98755 × 10^9 N · m2 /C^2 . Answer in units of V.

Answer 1

Answer:

The electric potential is  15.23 V

Explanation:

Given;

charge Q = 8.473 nC = 8.473 x 10⁻⁹ C

position of the charge, r = 5 m

Coulomb constant is 8.98755 × 10⁹ N·m² /C²

Electric potential is given as;

$V= \frac{KQ}{r} = \frac{8.98755 X10^9 X 8.473X10^{-9}}{5}\\\\V = 15.23 V$

Therefore, a charge of 8.473 nC uniformly distributed along the x-axis from −1 m to 1 m, the electric potential (relative to zero at infinity) of the point at 5 m on the same axis is 15.23 V.
