1) Calculate the electric field a distance of 6.0 mm away from a +3.0 uC charge. Then, calculate the force on a -8.0 uC charge placed at this point. (k = 9 x 109 Nm2/C2) 2) What does the ammeter read in the circuit below? 1002 30V 500 502 A I Problems 3 - 5 are related to the following situation: A proton traveling to the right moves in- between the two large plates. A vertical electric field, pointing downwards with magnitude 5.0 N/C, is produced by the plates. 3) What is the direction of the force on the proton when between the plates? 4) Draw the electric field lines on the diagram. 5) If the electric field is 5.0 N/C, what is the acceleration and direction of the proton in the region of the plates? (e = 1.6 x 10-19 C, mp = 1.67 x 10-27 kg, k =9 x 109 Nm2/C2)5) If the electric field is 5.0 N/C, what is the acceleration and direction of the proton in the region of the plates? (e = 1.6 x 10-19 C, mp = 1.67 x 10-27 kg, k= 9 x 109 Nm2/C2) Problems 6 - 9 are related to the following situation: In the circuit shown here, the battery produces an emf of 5 V and has an internal resistance of 0.7 0. 20 + 10 I 6) Find the total resistance of the circuit.7) Find the current drawn from the battery. 8) Determine the terminal voltage of the battery. 9) Show the proper connection of an ammeter and a voltmeter that could measure voltage across and current through the 1 2 resistor.
