if the lenth of a wire conductor is doubled,by stretching it keeping the potential diffrence across it constant,by what factor does the drift speed of electron change ?

@apoorvk @ash2326 please figure it out.

OpenStudy (apoorvk):

Assuming that the diameter remains the same or suffers a negligible change?

OpenStudy (anonymous):

should the answer be "reduced by half" ?

OpenStudy (ash2326):

Drift velocity is inversely proportional to the length for constant value of V potential difference. Thus, if the length of the conductor is doubled drift velocity will be halved. The resistance of conductor is directly proportional to the length of the conductor. Thus, if length is doubled resistance will also be doubled.
