An electron beam projected along positive x-axis deflects along the positive y-axis. If this deflection is caused by a magnetic field, what is the direction of the field?
Answers
❣️Hi❣️
Here is ur answer=>
F
is along position y-direction.q is negative and
v
is along positive x direction.
Therefore,
B
should be along positive z-direction.
‼️I hope it will help you ‼️
Direction of feild is towards postive Z axis
• If a particle with charge Q & Velocity V is projected in B then particle experience magnetic force .
• Magnetic force is always perpendicular to both velocity V and Magnetic feild B
• Particle under such force move along circular path.
• Direction of such force is given by Right hand palm rule .
• In which , thumb points towards direction of motion of charged particles , palm points towards direction of Force & rest of fingers points towards direction of feild.
• In case of negatively charged body, upper palm is considered & in case of positively charged body lower palm is considered .
• In this case, Since particle deflects along postive Y axis , so, Direction of magnetic force is towards postive Y axis & motion of e- was in X axis then , Direction of magnetic field will be towards postive Z axis
