Solution:
The potential difference between two points is independent of the reference level of potential because the change in reference shifts both potentials by the same constant value.
A point charge is placed at origin. Assuming potential to be zero at infinity, potential difference at two point A and B is found to be 10 V i.e., \(V_A - V_B = 10 \text{V}\). Now if the reference at infinity is changed to 10 V, then \(V_A - V_B\) will be
