Two plates (placed horizontally) oppose one another with the upper plate having a diameter of 25 cm and the lower having a diameter of 0.5 m. A small particle ‘A’ of mass (4 \times 10^{-15}) kg carrying a positive charge of (3 \times 10^{-19}) C is released at the upper plate. a)what's the electric force acting on the particle,b) calculate the kinetic energy of the particle when it reaches the lower plate.
