Question

On interchanging the resistances, the
balance point of a meter bridge shifts
to the left by 10 cm. The resistance of
their series combination is 1k  . How
much was the resistance on the left
slot before interchanging the
resistance?

Answer 1

Explanation:

R1 /R2 = l / 100- l

On interchanging

R2/ R1 = (l -10)  / 100 - ( l-10)

Solving we get l= 55cm

Putting the value for 1st reaction

R1 = 550

R2 = 450

Answer 2

Answer: R1=550

R2=450
