Physics-Magnetic Force on Current
NEET Physics Magnetic Force on Current Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Lorentz force | (i) F = I l × B |
| (b) Cyclotron frequency | (ii) F = q (v × B) |
| (c) Force on a conductor | (iii) ν_c = (qB)/(2πm) |
| (d) Work done by magnetic force | (iv) Zero |
A
a-ii, b-iii, c-i, d-iv
B
a-i, b-ii, c-iii, d-iv
C
a-ii, b-iv, c-i, d-iii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The Lorentz force is defined as F = q (v × B), the cyclotron frequency is given as ν_c = (qB)/(2πm), the force on a conductor is F = I l × B, and no work is done by magnetic forces, which is zero.
