What is the maximum value of the magnetic field at a distance of 2.5 m from a light bulb that radiates 100 w of single-frequency sinusoidal electromagnetic waves uniformly in all directions? (ε0 = 8.85 × 10-12 c2/n ∙

T

Explanation:

 = Power of the bulb = 100 W

 = distance from the bulb = 2.5 m

= Intensity of light at the location

Intensity of the light at the location is given as

= 1.28 W/m²

= maximum magnetic field

Intensity is given as

T

whichever one it is, it's definitely not one that you included on the list you provided.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
