A resistance wire connected in the left gap of a metre bridge balances a 10 resistance in the right gap at a point which divides the bridge wire in the ratio 3:2. If the length of the resistance wire is 1.5 m, then the length of 1
of the resistance wire is:
Option: 1
Option: 2
Option: 3
Option: 4

For a meter bridge
From question
I.e For 1.5 m long wire its total resistance is 15
So using the unitary method
The length of
resistance wire will be =
