Question
A proton enters a perpendicular uniform magnetic field B at origin along the positive x axis with a velocity v as shown in the figure. Then it will follow the following path. [The magnetic field is directed into the paper].
Options
It will continue to move along positive x-axis.
It will move along a curved path, bending towards a positive x-axis.
It will move along a curved path, bending towards negative y-axis.
It will move along a sinusoidal path along the positive x-axis.
Solution
It will move along a curved path, bending towards a positive x-axis.
Explanation:
According to Right Hand Rule, force will act upward causing particle to follow curved path bending along positive x-axis.
