Acceleration of an object is depended upon the net force acting open the object and the mass of the object
there is a relation between intensity of light beam and the magnitude of electric field.<span>I=(1/2)c<span>ϵo</span>n<span>E2</span>=P/π<span>r2</span></span>
<span><span>E2</span>=2P/c<span>ϵo</span>nπ<span>r2</span></span>
E= magnitude of electric field
n= refractive index of medium

</span></span>energy= power*time
= P*(1m/speed of light)<span><span>energy=(P∗1m)/c</span></span>
