With OD=75cm, the galvanometer gives no deflections when OC is 50cm. If D is moved to touch the end of wire S, the value of OC for which the galvanometer shows no deflection is 62.5cm. The emf of cell B is 1.0V. Calculate (i) the potential difference across O and D when D is at 75cm mark from O (ii) the potential difference across OS when D touches S (iii) internal resistance of cell A (iv) the emf of cell A
