You're on a roll — Here are the solutions for the requested questions: Question 11: Meter Bridge Experiment Step 1: Set up the balance condition for the initial state. In a meter bridge, the balance condition is R_leftR_right = (l)/(100-l). Initially, the null point is at l_1 = 75 cm from terminal A. Resistance R is in the left gap and unknown resistance X is in the right gap. (R)/(X) = (75)/(100-75) = (75)/(25) = 3 So, R = 3X (
