Question

A Piatma is a very hot gas comprised of freely moving positive and negative suale particles that are in random motion. Which of the following microscopic properties, together alwama held to have an observable macroscopic effect on the plasma when the plan is placed in the region that contains the magnetic field?
A. The particles have subatomically mal dimensions
B. The particles are charged
C. The particles are not all classified as fundamental particles
D. The particles are in random motion

Answer 1

Answer:

B. The particles are charged

Explanation:

We know that a moving charge particle in magnetic field experiences a magnetic force given by :

$\vec F = q (\vec v \times \vec B)$

In the context, a very hot gas of piatma consists of freely moving positive particles as well as negative particles. Now when the plasma is placed in the region of a magnetic field, then it experiences a force and thus it shows that the particles are charged particles.

Hence , option (B) is correct.
