NEET Physics Maxwell's Equations MCQ Question
Type: MCQ-numerical-Medium-Class 12
If a plane electromagnetic wave travels in free space along the x-direction and has a magnetic field component B_y = (3 × 10^−8) T, what is the corresponding electric field E?
A
9 V/m
B
6 V/m
C
3 V/m
D
12 V/m
Correct Answer
Option A
Detailed Explanation
Using the relationship E = cB, where c is the speed of light (3 × 10^8 m/s), E = 3 × 10^8 × 3 × 10^−8 = 9 V/m.
