Ball #1 and Ball #2 are both the same size. Ball #1 has a charge of +6 e (e is the fundamental charge) and ball #2 is neutral. When the two balls are connected by a conducting wire, then 3 electrons move form #2 to #1 O3 protons move from #2 to #1 O 3 electrons move from #1 to #2 O3 protons move from #1 to #2. 6 electrons move from #2 to #1

Anthea rubs two latex balloons against her hair, causing the balloons to become charged negatively with 2.0 x 10-6 C. She holds the balloons distance of 0.70 m apart. What is the electric force between the two balloons? 3.7*10^4 N 8*10^-12 N O 5*10^-2 N O 7.3*10^-2 N

À student observes a demonstration involving an interaction between a neutral metallic sphere suspended from a string and a negatively charged insulating rod. The student makes the following statement: "As the negatively charged rod nears the sphere, it causes the electrons in the sphere to move away from the rod. The side of the sphere nearest Insulating to the rod becomes positively charged while the other side becomes negatively charged. So the sphere will be attracted toward the rod. If they touch, the sphere will swing back since they will both become neutral." Neutral conducting sphere rod What, if anything, is wrong with this statement? If something is wrong, explain the error and how to correct it. If the statement is valid, explain why.

A proton is launched from an infinite plane of charge with surface charge density -4.30×10-6 C/m2. If the proton has an initial speed of 3.00×107 m/s, how far does it travel before reaching its turning point? 3.50×10-7 m 19.3 m 6.44×10-7 m 38.7 m
