Determine the electric potential energy for the array of three charges shown in the drawing, relative to its value when the charges are infinitely far away. (Let q1 = 8.48 µC, q2 = 19.2 µC, and q3 = -16.1 µC.)
To determine the electric potential energy for the array of three charges, we need to calculate the work done to assemble the charges from an infinite distance away. The electric potential energy is defined as the work required to bring the charges together.
We can use the formula for the electric potential energy of a system of charges:
U = k * (q1*q2/r12 + q1*q3/r13 + q2*q3/r23)
where U is the electric potential energy, k is Coulomb's constant (k = 8.99 x 10^9 Nm²/C²) and r12, r13, and r23 are the distances between the charges.
From the given information, we know the charges q1 = 8.48 µC, q2 = 19.2 µC, and q3 = -16.1 µC.
To find the distances between the charges, we need more information or a diagram. Please provide additional details or include a drawing so we can proceed with the calculations.
