In a meter bridge experiment, null point is obtained at 20 cm from one end of the wire when resistance X is balanced against another resistance Y. if X < Y, then where will be the new position of the null point from the same end, if one decides to balance a resistance of 4X against Y?
- 50 cm
- 80 cm
- 40 cm
- 70 cm
Answer
(A) 50 cm
