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?

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: R1=550
R2=450
