Three Particles Lie on the X Axis: Particle 1, with a Charge

question 55

Multiple Choice

Three particles lie on the x axis: particle 1, with a charge of 1 * 10^-8 C is at x = 1 cm, particle 2, with a charge of 2 * 10^-8 C, is at x = 2 cm, and particle 3, with a charge of -3 * 10^-8 C, is at x = 3 cm.The potential energy of this arrangement, relative to the potential energy for infinite separation, is:

• A)"+4.9 * 10^-4 J"
• B)"-4.9 * 10^-4 J"
• C)"+8.5 * 10^-4 J"
• D)"-8.5 * 10^-4 J"
• E)"0 J"
