B, A, C​

Answer 1

Answer:

In the figure given below, the magnetic field strength at point A, B and C in the increasing order will be B, C, A

Answer 2

The magnetic field strength at point A, B and C in the increasing order will be A, B, C.

• The expression for the radius of the circular path of the particle is,
• r = mv/Bq
• where,
• m is the mass of the particle
• v is the speed of the particle
• B is the magnetic field
• q is the charge of the particle.
• as it is clear that,
• r ∝ 1/B
• the greater the radius, weaker the magnetic field strength.
• Thus as given the radius of A, B and C as, A < B < C.
• Thus, C < B < A will the order of the magnetic field strength.
• Option A, B, C is correct.
