Solving a problem in physics section 71 point 69 electr

69. The potential difference between the plates of a flat capacitor is 280 V. The surface charge density on the plates is 4.95 ∙ 10−11 C / cm2. The area of each plate is 100 cm2. Find: 1) the field strength inside the capacitor; 2) the distance between the plates; 3) the speed that the electron will receive, having passed in the capacitor the path from one plate to another.
