Q1. An electric field of 8.55x10^5 V/m is desired between two parallel plates, each of area 35.00 cm^2 and separated by 2.45mm of air. What charge should be on each plate?
Q2. An alpha particle (charge = +2e) is sent at high speed toward a nucleus (charge = 74e). What is the electric force acting on the alpha particle when it is 2 x 10-14 m from this nucleus?
