In the circuit shown in fig. the potential difference between the points C and D is balanced against 40 cm length of potentiometer wire of total length 100 cm. In order to balance the potential difference between the points D and E The jockey to be pressed on potentiometer wire at a distance of

A

`16cm`

B

`32cm`

C

`56 cm`

D

`80cm`

Text Solution

Verified by Experts

The correct Answer is:
B
`(V_(1))/(V_(2))=(iR_(1))/(iR_(2))=(l_(1))/(l_(2))`
`(5)/(4)=(40)/(l_(2))`
