Suggested solution:
O = 3.0 cm, u = -14, f = -21 cm On simplification, v = -8.4 cm The image is erect, virtual and located 8.4 cm from the lens on the same side as the object. As the object is moved away from the lens, the virtual image moves towards the focus of the lens but never beyond. The image pro..

. Therefore, for a mode of the substance deposited i.e., for m = M, where M is the relative atomic mass, the total charge flowing through the circuit is N A pe, where N A is the Avogadro's number. Thus, M = Z N A pe or Z = M/N A ep Where M/P is the equivalent mass of the substance. Thus Faraday's s..
