Physics

The Circular Motion

Assertion :A ...

Question

Assertion :A proton moves horizontally towards a vertical long conductor having an upward electric current. It will deflect vertically downward. Reason: Seeing the proton and the conductor from the side of the proton, the magnetic field at the site of the proton will be be towards right. Hence the force $\to F = q \to v \times \to B$ will deflect the proton vertically downward.

Both Assertion and Reason are correct and Reason is the correct explanation of Assertion

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation of Assertion
Seeing the proton and the conductor from the side of the proton, the magnetic field at the site of the proton will be be towards right. Hence the force $\to F = q (\to v \times \to B)$ will deflect the proton vertically downward.

Assertion: A proton and an $α$ - particle are projected with the same kinetic energy at right angle to a uniform magnetic field, then the $α$ - particle will move along a circular path of smaller radius than the proton.

Reason : $B q v = \frac{m v^{2}}{r}$ holds good for the charged particle moving in a circular path in a uniform magnetic field.
