Question

a beam of alpha particles is projected into a magnetic field if the direction of magnetic field is along the velocity of charged particles the particles get

Answer 1

Explanation:

The direction of magnetic field is along the direction of motion of the charge particles, so angle will be 0

∘

.

∴ Force F=qvBsinθ

=qvBsin0

=0(∵sin0=0)

So, there will be no change in the velocity.
