Physics-Magnetic Force on Current
NEET Physics Magnetic Force on Current Match the Following Question
Type: Match the Following-match the column-Easy-Class 12
Match Column-I with Column-II.
Column-I Column-II (a) Magnetic torque NIAB (i) Tendency to rotate the coil (b) Restoring torque kφ (ii) Balance magnetic torque (c) Angular deflection φ (iii) Indication on scale (d) Torsional constant k (iv) Restoring torque per unit twist
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The magnetic torque NIAB tends to rotate the coil (a-i), and the restoring torque kφ balances it (b-ii). The angular deflection φ is indicated on the scale (c-iii), and the torsional constant k is defined as the restoring torque per unit twist (d-iv).
