A 4.80 g bullet moves with a speed of 170 m/s perpendicular to the Earth's magnetic field of 5.00×10−5T. Part A
If the bullet possesses a net charge of 1.06×10−8 C , by what distance will it be deflected from its path due to the Earth's magnetic field after it has traveled 1.00 km ?

Explanation:

m = Mass of bullet = 4.8 g

v = Velocity of bullet = 170 m/s

B = Magnetic field of Earth =

q = Charge of bullet =

a = Acceleration

Time the bullet will be in the air for is

Force is given by

Magnetic force is given by

So

From the linear equations of motion we have

The defelection of the bullet is
