उत्तर
An alpha particle enters a uniform magnetic field as shown. The direction of force experienced by the alpha particle is out of the page.
Explanation:
According to Fleming's Left-Hand Rule, the current flows in the direction of the alpha particle, the field points in the direction of the paper's right side, and the force is directed out of the paper by the thumb.
