Answer:
(a). The magnitude of the magnetic force on a proton is
The direction of force in negative y direction.
(b). The magnitude of the magnetic force on a proton is
The direction of force in positive y direction.
Explanation:
Given that,
Velocity
Magnetic field
(a). For proton,
We need to calculate the force
Using formula of force
Put the value into the formula
Negative sign shows the direction of force in negative y direction
The magnitude of the magnetic force on a proton is
(b). For electron,
Using formula of force
Put the value into the formula
The direction of force in positive y direction
The magnitude of the magnetic force on a proton is
Hence, This is the required solution.
