When a wire is stretched and its radius becomes `r//2` then its resistance will be

The resistance of a wire is 2Omega . If its is stretched to double its length then its resistance will be _______ (fill in the gap)

A wire 1m long has a resistance of 1Omega . If it is uniformly stretched, so that its length increased by 25% then its resistance will become

A wire of radius r has resistance R. If it is stretched to a radius of (3r)/(4) , its resistance becomes

A wire of resistance R is uniformly stretched until its radius is halved. Its new resistance is

The resistance of a wire is 2 Omega . The wire is stretched to doubel its length. Now the resistance of the wire will become

If a wire of resistance 1Omega is stretched to double its length, then the resistnance will become

The resistance of wire of length l and area of cross-section a is x ohm. If the wire is stretched to double its length, its resistance would become:
