The resistances in the left and right gap of a metre bridge are 40 and 60 respectively. When the bridge is balanced, the distance of the null point from the centre of the wire towards left is

Options

  1. A5 cm
  2. B10 cm
  3. C15 cm
  4. D20 cm

Correct answer

B. 10 cm

Step-by-step solution

From the given data, aligned & 40 60 = 50-l 50+l & 2000+40 l=3000-60 l & 100 l=1000 & l=10 ~cm aligned
