Dimensions of a block are 1cm1cm100cm. If specific resistance of its material is

3 107ohmm, then the resistance between the opposite rectangular faces is


Relation between R, \rho, l, A is R=\rho \frac{l}{A} .
Here, \rho = (3)10^{7} ohm-m, l=10^{-2} m and A=10^{-2}m^{2}.
Substituting the above values, R=(3)10^{7} ohm.
