Use the formula a = |q|*v*B / m, where q is the charge, v is the velocity, B is the magnetic field, and m is the mass. This is alos equal to a = F / m.Since the velocity is not given, use the formula v = (2*KE / m)^(1/2).eport Abuse.

So, for this current, the drift velocity of electrons is about a tenth of a millimetre per second: pretty slow! b) Calculate the drift velocity of electrons in a copper wire of cross-sectional area 1 mm 2 when a current of 2.5 A flows through it.harge carried by electrons in cylinder = n Ã A Ã v Ã t Ã Q. This is the amount of charge which passes point A in time t. To find the current which this represents, we need to find the rate at which the charge has flowed.
