A wire connected in the left gap of a meter bridge balance a `10Omega` resistance in the right gap to a point, which divides the bridge wire in the ratio 3:2. If the length of the wire is 1m. The length of one ohm wire is

A

0.057m

B

0.067m

C

0.37m

D

0.134m

Text Solution

Verified by Experts

The correct Answer is:
B
`"Here", (R )/(S) =(3)/(2),S=10Omega`
`therefore R=(3)/(2) xxS=(3)/(2)xx10=15Omega`
As the length of wire is 1m.
length of one ohm wire=1//15=0.067m
