A potentiometer wire PQ of 1 m length is connected to a standard cell E1. Another cell E2 of emf 1.02 V is connected with a resistance 'r' and switch S (as shown in figure). With switch S open, the null position is obtained at a distance of 49 cm from Q. The potential gradient in the potentiometer wire is :
  • a)
    0.02 V/cm
  • b)
    0.01 V/cm
  • c)
    0.03 V/cm
  • d)
