A particle of charge +q and mass m moving under the influence of a uniform electric field E and a magnetic field B  enters in I quadrant of a coordinate system at a point (0, a) with initial velocity v  and leaves the quadrant at a point (2a, 0) with velocity - 2v . Find
Rate of work done by both the fields at (2a, 0)
    Correct answer is '0'. Can you explain this answer?

    From the work- energy theorem
    W=△K.E.
    ⇒qE.2a=(1/2)​m[4υ2−υ2]
    ⇒E=(3/4)​( mυ2​/qa)
    At P rate of work done by E field will be 
    =F.υ=(qE)(υ)cos0°
    =(3/4)​( mυ3/a​)
    At Q rate of work done
    =F.υ=(qE)(2υ)cos90°=0
    And work done by the magnetic field is always zero.
