Option 2: a. An electron is moving at a speed of 4.45 x 105 m/s from north to south in a magnetic field that runs from [NE] to [SW]. If the magnetic force balances the gravitational force on the electron, determine the strength of the magnetic field. b. Now consider a 50.0 cm long wire with a mass of 60.0 g that carries a current of 15.0 A from north to south. The uniform magnetic field is perpendicular to the above- mentioned wire. What the minimum magnetic field strength and direction that will balance the weight of the wire

Question
Option 2:
a. An electron is moving at a speed of 4.45 x 105 m/s from north to south in a magnetic
field that runs from [NE] to [SWJ. If the magnetic force balances the gravitational force
on the electron, determine the strength of the magnetic field.
b. Now consider a 50.0 cm long wire with a mass of 60.0 g that carries a current of 15.0
A from north to south. The uniform magnetic field is perpendicular to the above-
mentioned wire. What the minimum magnetic field strength and direction that will
balance the weight of the wire?
