Answer:
The electric and magnetic field are 6.34 N/C and .
Explanation:
Given that,
Distance = 4.5 m
Time = 2.84 μs
We need to calculate the acceleration
Using equation of motion
The distance covered by the electron is
When, the electron at rest
Where, s = distance
a = acceleration
t = time
Put the value into the formula
We need to calculate the electric field
Using formula of the electric field
Put the value into the formula
We need to calculate the magnetic field
Using formula of magnetic field
Put the value into the formula
According to the right hand rule,
The direction of magnetic field is outward because the direction of force is upward.
Hence, The electric and magnetic field are 6.34 N/C and .
