D) if you had available a sensitive spring scale, using a light string you could have hanged the bolt from it to measure its mass in air. then, when the bolt was dipped in water, you could have measured the new mass of the bolt. with reference to archimedes principle, would you expect the mass of the bolt in water to be greater, the same, or < the mass in air? explain your reasoning.

The two metal spheres in the figure are connected by a metal wire with w switch in the middle. initially the switch is open. sphere 1, with the larger radius, i'd given a positive charge. sphere 2, with the smaller radius, is neutral. then the switch is closed. afterward, sphere 1 has charge q1, is at potential v1 and the electric field strength at its surface is e1. the values for sphere 2 are q2, v2, and e2. a. is v1 < ,> , or = to v2? explain. b. is q2 < , > , or = explain? c. is e1 < ,> ,or = to e2? explain?
