Document Summary
2 pt two charged spheres are 8. 57 cm apart. They are moved closer to each other enough that the force on each of them increases 4. 30 times. How far apart are they now? (in cm: a(cid:13) 0. 445. The plate on the right is positively charged: a(cid:13) true. The potential energy of a positive charge moved from point a to point b will decrease: a(cid:13) true. B(cid:13) false: a, true, b, false, b, false, b, false, a, true. Choose true or false for each statement below about the uni- form electric eld shown above. A negative charge at point b is at a lower potential than point c: a(cid:13) true. The kinetic energy of a negative charge moved from point a to point b will increase: a(cid:13) true. The electrostatic force on a charge is greater at point a than at point b. A constant electric eld of magnitude e = 138 v/m points in the positive x-direction.
