The work done by an electric force in moving a charge from point A to point B is 2.74 times 10-3 J. The electric potential difference between the two points is VA - VB = 57.0 V. What is the charge? C A moving particle encounters an external electric field that decreases its kinetic energy from 9460 eV to 7540 eV as the particle moves from position A to position B. The electric potential at A is -52.5 V, and the electric potential at B is +28.9 V. Determine the charge of the particle. Include the algebraic sign (+ or -) with your answer. C The drawing shows a square, each side of which has a length of L = 0.25 m. Two different positive charges q1 and q2 are fixed at the corners of the square. Find the electric potential energy of a third charge q3 = -1.23 times 10-8 C placed at corner A and then at corner B. The drawing shows a graph of a set of equipotential surfaces seen in cross section. Each is labeled according to its electric potential. A +3.1 times 10-7 C point charge is placed at position A. Find the work that is done on the point charge by the electric force when it is moved about the the following ways. from A to B J from A to C J An electron is released from rest at the negative plate of a parallel plate capacitor and accelerates to the positive plate (see the drawing). The plates are separated by a distance of 2.6 cm, and the electric field within the capacitor has a magnitude of 3.9 times 106 V/m. What is the kinetic energy of the electron just as it reaches the positive plate? KEpositive = A capacitor has a capacitance of 2.12 times 10-8 F. In the charging process, electrons are removed from one plate and placed on the other plate. When the potential difference between the plates is 445 V, how many electrons have been transferred? electrons
