In a potentiometer experiment, the null point is obtained at a particular point for a cell on potentiometer wirelong. If the length of the potentiometer wire is increased without changing the cell, the balancing length will (Driving source is not changed)
Options:
Answer:
A
Solution:
On increasing the length of the potentiometer wire, the potential gradient will decrease, hence longer balancing length is required.
