please answer questions 1-5 on a separate sheet of paper with explanations !

1. Two very large plates are separated by a distance As. Each plate has a surface area of 1 m\". The plates are connected by a battery, which puts 3 x 10~ C on plate A and 3 x 10~* C on plate B, as shown in the figure. A proton is released at rest from the inner edge of the positively charged plate. When it reaches the negatively charge plate, it has a speed of 3.7 x 10* m/s. (a) The battery provides a voltage difference between these two plates. What is the voltage of the battery? (b) What is the magnitude of the electric force experienced by the proton? (c) What is the distance between the two plates? F A B 3x10%C | -3x10C As (a) find the current Iy and I3 in the following circuit. 5. A 2-02 light bulb is connected to a 6-volt battery and left on for 20 minutes, (b) find the voltage difference across the 2- resistor. (a) What is the power (W) of the light bulb? (c) find the voltage difference across the 3-{) resistor. 2. For the following circuit, (b) How much charge flows through the light bulb in this time? What total battery energy has been used? (d) find the voltage difference across the 10-) resistor. L 2n 7v 100 3Q 50 40Q 3. Three charges are placed in locations shown in the diagram below. (a) What is the electric field (magnitude and direction) at point P? Answer the direction in terms of the angle relative to the positive side of the x-axis. (b) A negative charge of -30 nC is placed at point P. What is the electric force (magnitude and direction) on the -30 nC charge? Answer the direction in terms of the angle relative to the positive side of the x-axis. +20nC +10 nC 4. An infinite sheet is placed next to a point charge, as shown in the figure below. The inifite sheet as a surface charge density = 2 x 10 C/m?. Find the magnitude and direction of the electric field at point "x". Express the direction in terms of up, down, left, or right. o=2x10?C/m? 5x10%C 3em Scm
