HEY. I NEED YOUR HELP SOLVING THESE TWO PROBLEMS WITH EXPLAINATION AND STEP BY STEP WITH FINAL ANSWER PLEASE. CLEAR HAND WRITTEN PLEASE. THANKS

Question 17 The electric potential at the origin of an xy-coordinate system is 40 VA-8.0-uC charge is brought fromx +oo to that point. What is the electric potential energy of this charge at the origin? Not complete Points out of 1.00 Select one: F Flag queetion O A. 3.2 x 10 J O B. -3.2 x 10 J O C. 40 u D. -40 HJ O E. 8.0 HJ Check An 800 V/m electric field is directed along the +x-axis. Ifthe potential at x om is 2000 v what is the potential at x 2 m? Question 18 Not complete Select one: Points out of 1.00 O A. 800 V P Flag question B. 1000 V O C. 600 V D. 200 V E. 400 V Check

Explanation / Answer

17. Electric PE = Change in potential * charge = (40-0)V * -8*10-6 C = -3.2*10-4 J (option B)

18. Change in potential, V = E * d (because E = V/d) => V = 800 V/m * 2m = 1600 Volts

Hence Voltage at x=2m = 2000-1600 = 400 V (Option E)
