The uniform electric field intensity between the two plates of a parallel plate capacitor is \(1 \times 103 \mathrm{Vm}^{-1}\) acting vertically upwards as shown in the figure.


The plates are sufficiently long and have separation \(2 \mathrm{~cm}\). A particle of negative charge \(1 \mu \mathrm{C}\) and mass \(2 \mathrm{~g}\) is projected at an angle \(45^{\circ}\) with the electric field from the lower plate with a velocity ' \(u\) '. The maximum velocity acquired by the particle, if it is not hit the upper plate is

1. A \(2 \mathrm{~ms}^{-1}\)
2. B \(1 \mathrm{~ms}^{-1}\)
3. C \(0.1 \mathrm{~ms}^{-1}\)
4. D \(0.2 \mathrm{~ms}^{-1}\)
