NASA uses a plane often called the "vomit comet" to simulate the weightlessness of space in astronaut training. The plane travels in circular arcs at a speed of v = 248 m/s. What is the radius the pilot must fly to create weightlessness as they go around the top of the circular arc?

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?
