Type: MCQ-numerical-Medium-Class 12
In a meter bridge experiment, the ratio of the left gap resistance to right gap resistance is 2 : 3, the balance point from left is
A
60 cm
B
50 cm
C
40 cm
D
20 cm
Correct Answer
Option C
Detailed Explanation
Using the formula for the meter bridge, P/Q = l/(100-l), where P/Q = 2/3. Solving gives l = 40 cm.
