The electric field of a plane electromagnetic wave is given by

\overrightarrow E = {E_0}{{\widehat i + \widehat j} \over {\sqrt 2 }}\cos \left( {kz + \omega t} \right)

At t = 0, a positively charged particle is at the point (x, y, z) =

\left( {0,0,{\pi \over k}} \right)

. If its instantaneous velocity at (t = 0) is

{v_0}\widehat k

, the force acting on it due to the wave is :
