15-30 8. Three charges start out infinitely far away from this triangle, and infinitely far away from each other. What is the

Answer 1

Answer #1

Here,

for the total work needed

total work needed = change in potential energy

total work needed = final potential energy - initial potential energy

total work needed = 9 *10^9 * 10^-6 * 10^-6 * (-8.2 * 5.7/0.013 + 5.7 * 3.4/0.0075 - 8.2 * 3.4/0.015)

total work needed = -25.8 J

the total work needed is -25.8 J
