Show your solutions. 1. What potential difference is needed to stop an electron that has an initial velocity v = 6.0 x 105m/s? 2. How strong is the electric field between two parallel plates 6.88mm apart if the potential difference between them is 220V? 3. An 8500-pF capacitor holds plus and minus charges of 16.5 x 10 C. What is the voltage across the capacitor? 4. How much charge flows from each terminal of a 12.0-V battery when it is connected to a 5.00uF capacitor? Instructions: 1. Rewrite the problems presented above in a separate sheet of neat paper. 2. Provide the necessary solutions to solving the problem. 3. Highlight the final answer and anything that is needed to be derived/ solved to answer each
