The shortest distance between equipotential lines of 4 V and 9 V in an electric field of 10 N/C is a. 50 m b. 2 m c. 0.5 m d. 0 Version A

Explanation / Answer

1.

If the object is negatively charged, that means the negative charge is more than the positive charges.

because, if the net charge is negative

That means

Total electron> total protons

Now, we know that protons can not be transferred.

It is more electrons have been brought to the object.
