In a region an electric field is setu!l with its strength `E = 15 N//C` and it makes an angle of `30°` with the horizontal plane as shown in figure. A ball having a charge 2C, mass 3kg and coefficient of restitution with ground 0.5 is projected at an angle of `30°` with the horizontal along the direction of electric field with speed 20 m/s. Find the horizontal distance travelled by ball from first hit with the ground to the second time when it hits the ground. `[70 sqrt(3)m]`
