WebJan 2, 2024 · To Find: Position of null point = l = ? Solution: Let l be the distance of the null point from the left end. For balanced metre bridge ∴ 10/ (80/9) = l / (100 – l) ∴ 9/8 = l / (100 – l) ∴ 9 (100 – l )= 8 l ∴ 900 – 9 l = 8 l ∴ 17 l = 900 ∴ l = 900/17 = 52.94 cm Ans: The null point is at 52.94 cm on the wire from the left end.
