Review (Figure 1) Make sure the angle setting in your calculator is "Degree". sin30º = 0.5 Before putting any charge at Origin. The configuration is shown in (Figure 1) 91 = -8.80 C 92 = 2.90 4C1 HC = 10-6C use k = 9.00 x 10' N/(m2 c) for the Coulomb Constant 91 = -8.80 uc q2 = 2.90 C 1 MC = 10-6C use k = 9.00 x 10 N/(m2 c2) for the Coulomb Constant. di = 0.320 m angle a = 26° d2 = 0.260 m = di = 0.320 m 0.260 m Q = 26° d2 = Part A - Calculate the electric POTENTIAL at the origin by charge q1. AZO XX vi i Use scientific notation is Newton/Coulomb N/C, NO NEED to enter unit. answer format: 1.234.10" , unit V1 = -2.475x105 v Submit Previous Answers Correct Important: If you use this answer in later parts, use the full unrounded value in your calculations. Part B - Calculate the electric POTENTIAL at the origin by charge 92. V2 = 1.004x105 v Submit Previous Answers Correct Correct answer is shown. Your answer 100384.62 V was either rounded differently or used a different number of significant figures than required for this part Important: If you use this answer in later parts, use the full unrounded value in your calculations.
m Review Part C - Calculate the TOTAL electric POTENTIAIL at the origin by charge 1 (Figure 1) and q2. Vtotal 91 = -8.80 uc 92 = 2.90 4C 1 HC = 10-6C use k = 9.00 x 10°N/(m2c2) for the Coulomb Constant. -1.471x105 v = dị = 0.320 m 2 = 26 º d2 = 0.260 m Submit Previous Answers Correct Correct answer is shown. Your answer -147115.38 V was either rounded differently or used a different number of significant figures than required for this part. Important: If you use this answer in later parts, use the full unrounded value in your calculations. Now put a Negative point charge q = -1.90 C at origin O. Complete comfiguration is shown in (Figure 2) Part D - Calculate the TOTAL electric POTENTIAL ENERGY (of q). Enter regular number, keep 4 digits after the decimal point. Unit is Joules (no need to enter) EP Etotal 0.2795 J (of a) = Submit Previous Answers Correct Important: If you use this answer in later parts, use the full unrounded value in your calculations.
