The drawings show three charges that have the same magnitude but may have different signs. In all cases the distance d between the charges is the same. The magnitude of the charges is |q| = 8.6 μC, and the distance between them is d = 3.8 mm. Determine the magnitude of the net force on charge 2 for each drawing. Calculate the electric potential energy with configuration of charges on the figur

The shaded region in the diagram is a region of uniform electric field. A negative charge Q = -2μC experiences a force in the region as shown by the arrow. At which point (A or B) does the charge have lower electric potential energy? Neglect gravity. i в. F None of the answer choices is correct. The charge has the same potential energy at both points A and B since the electric field is uniform (constant). O Point B has lower potential energy. Point A has lower potential energy.

An alpha particle (with a charge of +2 e and a mass of 6.64 x 1027 kg) is fired at a fixed gold nucleus (with a charge of +79 e ) from very far away. The alpha particle makes it a point a distance of 2.0 x 106 m away from the gold nucleus before flying backwards away. A. Determine the potential energy of the alpha particle and gold nucleus pair when they are 2.0 x 10-6 m apart. B. What is the kinetic energy of the alpha particle when it reaches this turning point? How do you know? C. What is the potential energy of the alpha particle and gold nucleus pair when they are very far apart? How do you know? D. Determine the initial speed of the alpha particle (when it was very far away from the gold nucleus).

Oppositely charged parallel plates are separated by 4.79 mm. A potential difference of 600 V exists between the plates. (a) What is the magnitude of the electric field between the plates? N/C(b) What is the magnitude of the force on an electron between the plates? N(c) How much work must be done on the electron to move it to the negative plate if it is initially positioned 2.18 mm from the positive plate? J
