To solve the problem, we will use the relationship established in a potentiometer experiment, which relates the e.m.f. of the cells to the balancing lengths. ### Step-by-Step Solution: 1. **Identify the given values:** - E1 = 2 V (e.m.f. of the first cell) - E2 = 1.5 V (e.m.f. of the second cell) - L1 = 120 cm (balancing length for the first cell) ...
