1. Calculate the magnitude of the electric field generated (8.4x10^0) m from an electron, giving your answer in N/C to 2 significant figures. Magnitudes must be positive.

2 You are designing an electron accelerator to bring a stationary electron to a speed of (6.74x10^6) m/s in a uniform electric field. If the distance travelled is (5.228x10^-2) metres, what must the magnitude of the electric field be in N/C?

3 A uniform electric field is created by applying a potential difference of (6.02x10^0) kV between parallel plates which are (3.3100x10^0) cm apart. Calculate the magnitude of the electric field in V/m

4 Calculate the potential in volts at a distance of (8.64x10^0) m from a point charge of (-7.2x10^0) C

please do QUICK and dont make the answer public, IT IS VERY IMPORTANT QUESTIONS PLEASE GET IT RIGHT
