NEET Physics Motional EMF Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Induced emf across a length dr of the rod (i) 0.4 G (b) Speed of rotation of the wheel (ii) 120 rev/min (c) Magnetic field strength at the place (iii) ε = B v l (d) Length of the spokes of the wheel (iv) 0.5 m
Choose the correct matching:
a-iii, b-ii, c-i, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-iv, c-ii, d-iii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The induced emf across a length dr of the rod is represented by ε = B v l (pair a-iii). The speed of rotation of the wheel is mentioned as 120 rev/min (pair b-ii). The magnetic field strength at the place is given as 0.4 G (pair c-i). The length of the spokes of the wheel is 0.5 m (pair d-iv).
