What is the maximum power that can be delivered by a 1.4cm diameter laser beam propagating through air?
answer is p=____W
Homework Answers
.The concept used to solve this problem is power and the relation between intensity and electric field strength.
Initially, use the expression for the maximum power delivered by the laser beam by substituting intensity and area and then use intensity formula in terms of maximum electric field and velocity of light.
Finally, find the value of the maximum power delivered by the laser beam.
The maximum power delivered by the laser beam is,
Here, I is the intensity of light and A is the area.
The expression for intensity is,
Here, 
is the maximum electric field strength, c is the velocity of light and
is the permittivity of free space
The area of the laser beam is,
Here, d is the diameter of the beam.

The dielectric strength of air, E = 3.0×106 V/m, is the maximum field that air can withstand before it breaks down and becomes conducting. How much charge can be placed on a spherical conductor with a 8.0- cm radius before the field at its surface exceeds the breakdown strength of the air? The answer to this section is 2.14×10-6 C. My question: What would be the electric potential at the surface of this conductor?
