The electric field of a wave is given by E=E0( i+j)/√2 cos(kz +wt) .At t=0, a positively charged particle is at the point (x,y,z) =(0,0,pie/k).If it's instantaneous velocity at (t=0) is v0 (k) the force acting on it due to the wave is:(1) 0(2) parallel to(i+j)/√2(3) antiparallel to (i+j)√2(4) parallel to(k)
