Answer:
λ = 65.6 pm
Explanation:
Given that
λo = 65 pm
The initial energy of the electron
Now by putting the values
Eo=19.06 KeV
Given that kinetic energy KE= 0.84 KeV
Therefore the final energy
E= Eo - KE
E = 19.06 - 0.84 KeV
E= 18.22 KeV
The wavelength λ can be find as
λ = 6.56 x 10⁻¹¹ m
λ = 65.6 pm
Answer:
The magnetic field is upwards.
Explanation:
You have to use "Right-hand rule", but for electrons, the direction of the magnetic force should be reversed.
