Mathematics · Electromagnetic Waves
Radiation is emitted by a 1000 W bulb with an efficiency of 1.25%. It generates an electric field and a magnetic field at a point P, placed at a distance of 2 m from the bulb. The value of the peak electric field at P is x × 10-1 V m-1. What is the value of x rounded off to the nearest integer? [Take ε0 = 8.85 × 10-12 C2 N-1 m-2, c = 3 × 108 m s-1]
