An electron moving with a velocity v= 5.0 × 107 m/s i enters a region of space where perpendicular electric and a magnetic fields are present. The electric field is E= 104 V/m j. What magnetic field will allow the electron to go through the region without being deflected?

The magnetic field that will allow the electron to go through the region without being deflected is .

Explanation:

Given that,

Velocity of the electron,

Electric field,

We need to find the magnetic field that will allow the electron to go through the region without being deflected. It can be calculated as :

Here,

So, the magnetic field that will allow the electron to go through the region without being deflected is .
