In the figure seven charged particles are fixed in place to form a square with an edge length of 6.1 cm. How much work must we do to bring a particle of charge +1e initially at rest from an infinite distance to the center of the square? +2e -2e -Se +3e +e +Se x

An immovable charge Q₁ = +2.0µC is placed in fixed location at the origin on an (x, y) coordinate system. Another charge, Q₂ = +4.0μC is allowed to move near the first charge. How much work does it take to move this charge from it's starting location of (-3cm, 4cm) to the following locations and if the time to make this change is 10 ms how much power was output during each process: (a) (-1.5cm, 2cm) (b) (-6cm, 8cm) (c) (3cm, 4cm)

A square of particlesFour particles are attached to the four corners of a square whose edge measures L (see image). Particles A and B each have a positive charge q and particles C and D each have a negative charge -q. (a) What is the electrical potential energy of the system? (b) Is this energy positive or negative?

A point charge of 5.4 x 10-6 is held in place (initially at rest) at the origin. If a second point charge of -5.9 x 10-6  C is moved from its initial location of (0.48, 0) m to a final location of (1.3, 0) m, what is the change in potential energy of the system. Assume that the 2 point charges are isolated.

Three electrons form an equilateral triangle 1.99nm on each side. A proton is at the center of the triangle. What is the potential energy of this group of charges? Submit Answer Tries 0/10

In Figure (a), we move an electron from an infinite distance to a point at distance R = 2.50 cm from a tiny charged ball. The move requires work W = 2.81 × 10-13 J by us. (a) What is the charge Q on the ball? In Figure (b), the ball has been sliced up and the slices spread out so that an equal amount of charge is at the hour positions on a circular clock face of radius R = 2.50 cm. Now the electron is brought from an infinite distance to the center of the circle. (b) With that addition of the electron to the system of 12 charged particles, what is the change in the electric potential energy of the system? (a) Number i (b) Number i |R-| (a) Units Units < Det er (b) < A
