A particle , of mass `10^(-3)` kg and charge 1.0C, is initially at rest . At time t = 0 , the particle comes under the influence of an electric field `vec(E) (t) = E_(0) sin w t vec(i)` , where `E_(0) - 1.0 NC^(-1)` and `omega = 10^(3) rd d s^(-1)` . Consider the effect of only the electrcial force on the particle . Then the maximum speed m `s^(-1)` , attained by the particle at subsequent time is x . Find x .
