Question

A charge of 100uc is placed at a distance of 12cm from a charge of 200uc calculate the potential mid way between 2 charges

Answer 1

The midway between two charges is 450 х $10^{7}$

Given:

The charge of 100c at a 12cm from 200c

To Find:

The potential midway between the two charges

Solution:

V = $\frac{KQ}{r}$

V = $\frac{K(100)}{6(10)^-2} + \frac{K200}{6(10)^-2}$

V = $\frac{K}{6(10)^-2} (100+200)$

V = $\frac{9(10)^9}{6(10)^-2} (300)$

V =  450 х  $10^{7}$ volt

Hence, potential difference (v) is 450  х $10^{7}$ volt
