Calculation of Electric Field

To calculate the electric field at a distance of 3m from the electromagnetic radiation source, we need to use the formula:

E = (2P/4πε₀r²)¹/²

Where P is the average power output of the source, r is the distance from the source, and ε₀ is the permittivity of free space.

Substituting the values, we get:

E = (2 x 1500 W / 4π x 8.85 x 10⁻¹² F/m x (3 m)²)¹/²

E = 250 3 V/m

Therefore, the maximum value of electric field at a distance of 3m from the source is 250 3 V/m.

Explanation

The electric field strength decreases as the distance from the source increases. This is because the energy is spread out over a larger area as it travels away from the source. The formula used to calculate the electric field takes into account the power output of the source and the distance from the source. The permittivity of free space is a constant value that relates to the ability of a vacuum to support electric fields.

The answer to this question is (d) 250 3. This is because the calculation shows that the electric field at a distance of 3m from the source is 250 3 V/m. Therefore, this is the maximum value of electric field at that distance.
