Two charged metal plates in vacuum are 10cm apart. A uniform electric field of intensity `(45//16)xx10^(3)NC^(-1)` is applied between the plates. An electron is released between the plates from rest at a point just outside the negative plate.
(a) Calculate how long (t) will the electron take to reach the other plate?
(b) At what velocity (v) will it be electron take to hits teh other plate?

Explanation

Let's solve the problem step by step.

### Given Data:
- Distance between the plates, \( s = 10 \, \text{cm} = 0.1 \, \text{m} \)
- Electric field intensity, \( E = \frac{45}{16} \times 10^3 \, \text{N/C} \)
- Charge of an electron, \( q = -1.6 \times 10^{-19} \, \text{C} \)
- Mass of an electron, \( m = 9.1 \times 10^{-31} \, \text{kg} \)
