Answer:
Electron A It remains stationary, while electron B continues moving westward
Explanation:
The force acting on each electron is given by F = Bevsinθ where B = magnetic field strength, v = velocity of electron, e = electron charge and θ = angle between B and v
Force electron A, v = 0, and θ = unknown, so F = Be × 0 × sinθ = 0.
So, no force acts on it and thus, it does not move. It remains stationary.
Force electron B, v = constant, acceleration, a = 0 and θ = 180, so F = Bevsin180 = 0.
So, no net force acts on it and thus, it does not change direction. It continues moving westward.
The electron A remains at rest.
The electron B continues moving in the westward direction.
The magnetic force only acts on a moving charge.
The force acting on each electron is given by:
F = evBsinθ
where B is the magnetic field strength,
v is the velocity,
e is the charge on the electron
and θ is the angle between B and v
In the case of electron A;
v = 0, so:
F = 0.
Electron A does not experience any force and remains at rest.
The electron B is moving with a constant velocity, let's say v in the westward direction
The magnetic field B is in eastward direction,
so, angle between B and v is θ = 180°
The force on electron B is
F = evBsin180
F = -evB
Since the charge on electron e is already negative, the force F will be positive, which means in the direction of the motion of the electron, that is westward.
