an electron is moving at 10^6m/s in a direction parallel to 5A current flowing through na infinitely long straight wire separated by a perpendicaular distance of 10cm in air.calculate the magnitude of force experienced by the electron.

v=10^6m/s
I=5A
F=?
q=1.6*10^-19
d=10cm=0.1m
From chapter magnetic effects of current,we know,
B=meu nought.I/2?d
=4?*10^-7.5/2? into0.1
=10^-5T
F=qvB
F=1.6*10^-19 into 10^6 into10^-5
F=1.6*10^-18
So,the above given numerical value is the force experienced by the electron.
