A laser (electromagnetic wave) has the maximum electric field strength of 1.0x1011 V/m. What is the force the laser applies on a mirror (totally reflective) of 5.0 mm2 area? A. 2.76 x105N B. 1.21 x106N C. 1.94 x106N D.4.43 x105 N E. 7.82 x104N

The correct option is  D

Explanation:

From the question we are told that

  The maximum electric field strength is  

   The  area is  

Generally the force the laser applies is mathematically represented as
