A point source of electromagnetic radiation has an average power output of 800W.
(a) Find the maximum value of electric field at a distance 3.5 m from the source.
(b) What will be the maximum value of magnetic field?
(c) What will be the energy density at a distance at a distance 3.5m from the source?

Explanation

To solve the given problem step by step, we will address each part of the question systematically.

### Given Data:
- Average power output (P) = 800 W
- Distance from the source (r) = 3.5 m
- Speed of light (c) = \(3 \times 10^8 \, \text{m/s}\)
- Permittivity of free space (\(\epsilon_0\)) = \(8.85 \times 10^{-12} \, \text{F/m}\)
