MHT CET 2026 Physics question
In meter bridge experiment, two resistances X and Y in the two gaps give a null point dividing the wire in the ratio 2 : 3. When each resistance is increased by 30, the null point divides the wire in the ratio 5 : 6. The resistance X and Y are respectively
Answer: (A)
Solution
At balance of a meter bridge, , i.e. the ratio of the wire lengths. First case: , so let and . Second case: , so , giving $12k
