NEET Physics (general) MCQ Question
Type: MCQ-numerical-Medium-Class 12
A plane electromagnetic wave travels in free space with an electric field E = 7.5 ˆ j V/m. What is the magnitude of the corresponding magnetic field B?
A
2.5 × 10⁻⁸ T
B
2.5 × 10⁻⁷ T
C
2.5 × 10⁻⁹ T
D
2.5 × 10⁻⁶ T
Correct Answer
Option A
Detailed Explanation
The magnitude of the magnetic field B is calculated using B = E/c, where c = 3 × 10⁸ m/s, resulting in B = 2.5 × 10⁻⁸ T.
