Calculate the potential at the point P at a distance D=2.07 m from one end of the horizontal rod. Special note: You're going to have to take the difference between the potentials made by the positive and negative rods, which are similar numbers. That means that to get an accurate answer you need to keep more digits than usual while you're doing your calculation. For my answer I got 4.15799E11 V which was wrong

Consider two separate systems with four charges of the same magnitude q = 17 µC arranged in the vertexes of a square of length h = 20 cm, see the picture below. Calculate the electric potential at the center of the square (points A and C) and at the middle of the bottom side of the square (points B and D). y y q h q h A. B The potential at point A, VA = The potential at point B, VB = The potential at point C, Vc = = The potential at point D, VĎ : q q X Units V Units V Units V Units V Units J q Units J F h C c. Ꭰ How much work is required to move a -38 µC charge from point A to point B? The work required, Wä→ß = How much work is required to move a -38 µC charge from point C to point D? The work required, Wc→D = ✓✓. ✓✓. q -q O X

B A A 6 µC point charge is placed at the origin as shown in the figure above, where a = 2 cm, 6 = 2.4 cm, c = 1 cm, and d = 2.7 cm. Find the potential at the points A, B and C: VA V VB = V Vc = V

A plastic disk of radius R = 72.2 cm is charged on one side with a uniform surface charge density 7.67 fC/m², and then three quadrants of the disk are removed. The remaining quadrant is shown in the figure. With V = 0 at infinity, what is the potential in volts due to the remaining quadrant at point P, which is on the central axis of the original disk at distance D = 0.429 cm from the original center? D
