STATEMENT-1 The dimensional formula for relative velocity is same as that of the charge in velocity STATEMENT-2 [Relative velocity] = [Change in velocity] STATEMENT-3 In addition or subtraction of two physical quantities of same dimension, the result also have same dimensIon only.

A metal wire of cross-sectional area 1m m^(2) contains 5xx10^(22) electrons per cm^(3) . If the electrons move along the wire with average drift velocity 1m m//s , then the current in the wire is ( e=1.6xx10^(-19)C )
