The maximum electric field strength in air is 3.0 Mv/m . Stronger electric fields ionize the air and create a spark. What is the maximum power that can be delivered by a 1.5cm diameter laser beam propagating through air?

The value is  

Explanation:

From the question we are told that  

    The maximized electric field strength is  

     The diameter is  

Generally the cross -sectional area is mathematically represented as

 =>      

 =>      

 =>      

Generally the maximum power is mathematically represented as

Here c is the speed of light with value  

        is the permeability of free space with value
