The intensity of the sunlight that reaches Earth’s upper atmosphere is approximately 1400 W/m2. (a) What is the average energy density? (b) Find the rms values of the electric and magnetic fields. Some useful formulas: I = <> c, <>= 0 Erms2 = Brms2 /0, 0=8.854 x 10-12 C2/(N. m2) , 0= 4  x 10-7 T. m/A, c= 3 x 108 m/s.

(a) Average energy density is 4.67 × 10⁻⁶  J/m³

(b) The rms value of the electric field is 726.26 V/m

and the rms value of the magnetic field 2.42 × 10⁻⁶ T

Explanation:

The average energy density < u > is given by

< u > = I / c

Where I is the intensity and

c is the speed of light

From the question

I = 1400 W/m²

c = 3 × 10⁸ m/s

∴ < u > = 1400 W/m² /  3 × 10⁸ m/s

< u > = 4.67 × 10⁻⁶  Ws/m³ (NOTE: Ws = J)

< u > = 4.67 × 10⁻⁶  J/m³

This is the average energy density

(b) From the formula

From the question, = 8.854 × 10⁻¹² C²/N.m²

∴

This is the rms value of the electric field

For the rms value of the magnetic field

From

Then,

From the question, = 4π × 10⁻⁷ T.m/A

This is the rms value of the magnetic field

your answer would be fusion

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
