Suppose a 6.00 nC electric charge is in the beam. What is the maximum electric force (in N) it experiences? If the static charge moves at 300 m/s, what maximum magnetic force (in N) can it feel?

Complete Question

Electromagnetic radiation from a 3.00 mW laser is concentrated on a 2.00 mm2 area. Suppose a 6.00 nC electric charge is in the beam. What is the maximum electric force (in N) it experiences? If the static charge moves at 300 m/s, what maximum magnetic force (in N) can it feel?

The value are  

and

Explanation:

From the question we are told that

   The power of the laser is  

     The area is  ]

      The speed is  

    The magnitude of the electric charge is  

Generally the intensity of the beam is mathematically represented as

=>    

=>    

Generally the magnitude of the  electric field is mathematically represented as

Here c is the speed of light with value

          is the permittivity of free space with value  

=>  

Generally the maximum electric force is mathematically represented as

=>    

=>    

Generally the intensity of the beam can also be  mathematically represented as

Here B is the  magnetic field

        is the permeability of free space with value

So  

=>    

=>    

Generally the maximum magnetic force is mathematically represented as

=>        

=>        

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
