The uniform electric field intensity between the two plates of a parallel plate capacitor is 1 x 103 Vm−3 acting vertically upwards as shown in the figure, The plates are sufficiently long and have separation 2 cm. A particle of negative charge 1 µC and mass 2 g is projected at an angle 45° with the electric field front the lower plate with a velocity 'µ'. The maximum velocity acquired by the particle if it is not hit the upper plate is
