  1. Cute problems with voltage - Movement q q What work to bring a 6.00 C charge from infinity to halfway between the other two charges? 24.0 cm +1.50 C +1.50 C • Find initial voltage • Find final voltage • V = final - initial • ΔEp = W = ΔVq 1.35 J

  2. q q q q q q +1.5 C +1.5 C +6 C 16.0 cm 8.0 cm What work to bring a 6 C charge from halfway between the other two charges to 8.0 cm from the left charge? +6 C +1.5 C +1.5 C 24.0 cm

  3. Try this one q q q What work to bring a 13.0 C charge from halfway between the other two charges to 6.0 cm from the positive and 18 cm from the negative? +3.20 C +13.0 C -4.10 C 12.0 cm 12.0 cm Initial V -67425 V Final V 274700. V Change in V 342100. V Work 4.448 J +4.4 J

  4. Each grid is a meter. If charge A is -14.7 μC, and charge B is +17.2 μC, calculate the voltage at points g and h, and the amount of work needed to move a +3.40 μC charge from g to h. A B y Step 1- Find the voltage at g: (-28775.6 V) g x x h x 0.144 J
