For a and b below, roughly where is the electric field zero? Mark with an E. Roughly where is the potential zero? Mark with a V. (If is nowhere near the charges, indicate this.) (Be sure to be clear if it's just one point, or something else.) Then sketch the electric field lines (solid) and equipotential lines (dotted) around the two point charges. а. ь.
Can there be a point between two equal negative charges where the electric potential is zero? What about the electric field? How would the electric potential at a distance of 12 cm from a point charge compare to the electrical potential at 48 cm from the charge? Can two equipotential lines cross? Why or why not? The amount of energy stored in a capacitor depends on what factors?
Points: 1 13) Is it possible to have a zero electric potential between two positive charges along the line joining the two charges? A) Yes, if the two charges are equal in magnitude. B) No, a zero electric potential cannot exist between the two charges. C) Yes, regardless of the magnitude of the two charges. D) cannot be determined without knowing the separation between the two charges E) cannot be determined without knowing the magnitude of the charges Points: 3...
1- For a uniform electric field, how is the electric potential energy similar to the gravitational potential energy in a uniform gravitational? 2-If a positive charge and a negative charge moving the same way in an electric field have the same change in electric potential energy? 3-For a positive charge moving in an electric field, which direction of motion will cause the electric potential energy to increase? Decrease? Stay constant? 4-How would the answers to the previous question be different...

1. Problem: Electric Potential due to Point Charges Consider four point charges placed at the corners of a square of side s = 0.5 μm. Two charges, diagonally opposite each other, are +0.7 nC. Another of the charges is -12 nC. a) What will be the electric potential at the center of the square if the fourth charge is -6 nC (assume the conventional zero point definition for each individual charge throughout this problem)? b) What should the fourth charge...
