Question

an alpha particle gets deflected towards the west direction when it enters a region of an uniform magnetic field directed vertically downwards identify the direction initial moment of the alpha particle​

Answer 1

Explanation:

Greece had been part of the Ottoman Empire since the fifteenth century. The growth of revolutionary nationalism in Europe sparked off a struggle for independence amongst the Greeks, which began in 1821.

Answer 2

Answer:

If a positively charged particle moving in east direction enters a region of uniform magnetic field directed vertically upwards, it will move in a circular path with a uniform speed.

If a charged particle is moving in a direction perpendicular to a uniform magnetic field, then its trajectory will be a circle because the force F=qvB is always perpendicular to the velocity, and therefore centripetal.
