A point charge q1 = 5.24 x 10°° C is held fixed at the origin of a coordinate system.. second charge q2 = -4.54 x 106 C is initially at the coordinates (0.155, 0) m and is then moved to the coordinates (0.225, 0) m. What change in potential energy result

A point charge q1 = 4.00 nC is placed at the origin, and a second point charge q2 = -2.90 nC is placed on the x-axis at x-+ 21.0 cm. A third point charge q3 = 2.00 nC is to be placed on the x-axis between g1 and q2. (Take as zero the potential energy of the three charges when they are infinitely far apart.) %3D %3D %3D Where should q3 be placed between q1 and q2 to make the potential energy of the system equal to zero?

A small object with a charge of q = 11.0 µC travels from the origin to the point (x, y) = (20.0 cm, 50.0 cm) in the presence of a uniform electric field É = 250î V/m. Determine the following. %3D %3D (a) the change in the electric potential energy (in J) of the object-field system (b) the electric potential difference (in V) through which the object moves V

A uniform electric field of magnitude 395 N/C pointing in the positive x-direction acts on an electron, which is initially at rest. The electron has moved 2.90 cm. (a) What is the work done by the field on the electron? 1.83e-16 Your response is off by a multiple of teh. J (b) What is the change in potential energy associated with the electron? -1.83e-16 Your response is off by a multiple of ten. J (c) What is the velocity of the electron? 2.00e-24 Your response differs significantly from the correct answer.
