The potential gradient long the length of a unifrom wire is `10 "volt"//meter`. `B` and `C` are the two points at `30 cm` and `60 cm` point on a meter scale fitted along the wire. The potential diffenence between `B` and `C` will be

3 volt

0.4 volt

7 volt

4 volt

Text Solution

Verified by Experts

The correct Answer is:

Distance between two points = `60-30`
`=30cm=0.3m`
The potential graident = `10V//m`
`therefore` Potential difference = potential gradient `xx` length
`=10xx0.3=3V`
