Question

A cell with considerable internal resistance is connected directly across the terminals of the potentiometer wire. The potential gradient is now ‘G’. Now the potentiometer wire is replaced by another wire of same material but double the length and having the same radius as that of the original wire. The new potential gradient on the wire with the same cell connected as before is A) G/2 B) G C) lesser than G/2 D) greater than G/2 answer is D) greater than G/2 if anyone proved this answer i will mark them as brainliest
note: please give right answer
