Since V=(W/Q), more work will be done for a positive charge of two units as compared to positive charge of one unit, but the ratio ( W / Q ) is same. Therefore potential difference is same.

I only

II and IV

I and II

I, II and III

Since V=QW​, more work will be done for a positive charge of two units as compared to positive charge of one unit, but the ratio QW​ is same. Therefore potential difference is same.

Since $V = \frac{W}{Q}$ , more work will be done for a positive charge of two units as compared to positive charge of one unit, but the ratio $\frac{W}{Q}$ is same. Therefore potential difference is same.
