What speed would a +1.00 c particle need to have to travel in a straight line through a 5.00 t magnetic field that is directed into the screen and a 2.00 v/m electric field that is directed from top to bottom?
40.0 m/s
4.00 m/s
0.400 m/s
0.0400 m/s

i will report you if you give a cruddy answer - explain!

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?
