What is JEE Mock Test Questions and Solutions about?

1) The mean drift velocity of electrons (vP) in section P of a wire is twice the mean drift velocity (vQ) in section Q, which has half the diameter of section P. 2) In a metallic conductor of non-uniform cross-section, the current and drift speed remain constant along the length. 3) The magnitude of the induced electric field at point P decreases as 1/r2, where r is the distance from the center of the circular region with the time-varying magnetic field B(t).
