Initial resistance of wire is 'r'
After the wire is cut into two equal parts , resistance of each part becomes r/2
Now they are connected in parallel .
Let new resistance be r*
So , 1/r*=2/r+2/r
=4/r
r*=r/4
therefore the equivalent resistance in one fourth of the intial one
Hope this help you,,,,,,have a good day....!!
