What are the (time varying) amplitudes of the e and h fields if summer sunlight has an intensity of 1150 w/m2 in any town?
calculate the relative strength of the gravitational and solar electromagnetic pressure forces of the sun on the earth.

Explanation:

Given that,

Intensity = 1150 W/m²

(a). We need to calculate the magnetic field

Using formula of intensity

Put the value into the formula

Using formula of magnetic field

Put the value into the formula

(b). The relative strength of the gravitational and solar electromagnetic pressure forces of the sun on the earth

We need to calculate the gravitational force

Using gravitational force

Put the value into the formula

We need to calculate the radiation force

Using formula of force

Put the value into the formula

The gravitational and solar electromagnetic pressure forces of the sun on the earth

Hence, This is the required solution.

the correct choice is a .
