1.	The Hall coefficient of a specimen is 3.66 x 10^-4 m^3C^-1. If it’s resistivity is 8.93 x 10^-3 Ωm, what will be its mobility?(a) 0.01 m^2V^-1s^-1(b) 0.02 m^2V^-1s^-1(c) 0.03 m^2V^-1s^-1(d) 0.04 m^2V^-1s^-1
Answer» The correct choice is (d) 0.04 m^2V^-1s^-1 Easy explanation: We know, Mobility = Hall coefficient/resistivity Therefore, Mobility = 3.66 x 10^-4/8.93 x 10^-3 = 0.04 m^2V^-1s^-1.
