An electron beam enters a uniform magnetic field at right angles. State the direction in which this electron beam will deflect.Name and state the principal we use to determine the direction of force experienced by the electron beam. What would happen if instead of electron beam alpha particles enter the magnetic field with same velocity?
Answers
It will deflect in upward direction... alpha particle will deflect in downward direction...... the rule used is flemming's left hand rule
Answer:
electron beam: upwards
Principle used: Fleming's left hand rule
alpha particle: downwards
Explanation:
In case of electrons, which are negatively charged, so the direction will come out to be upwards, i.e. north using the Fleming's left hand rule.
But for alpha particle, which is a positively charged particle having two protons, the direction will come out to be opposite to that of the electron, i.e. downwards.
Fleming's left hand rule- It states that when a current carrying conductor is placed in a magnetic field, a force is experienced by the conductor due to the magnetic field whose direction is perpendicular to both the directions of the current flowing and the magnetic field.
