Ohm's law
Question

Statement 1: When a cell is charged by connecting its positive electrode with positive terminal of the charger battery then potential difference across the electrodes of cell will be smaller to the EMF of cell.

Statement 2: Potential difference across electrodes in a cell providing electric current is E = Ir, where E is EMF and r internal resistance.

Easy
Solution

V = E + ir when charging of cell take place.
