a) What are the electrons doing in this case? (b) What would the electrons do if the wire were replaced by a dry string that does not conductelectricity? (Are you absolutely sure? How could you find outwhether or not your answer is correct?) These are the questions attached to the image. Please answer both A & B. plastic rodIII. Conductors and InsulatorsSuspend the metal cup from the plastic rodattached to the stand and connect it as shown bymeans of a conducting wire to the knob of theelectroscope. Use a proof plane to make amomentary connection between the knob and thegrounded case (recall the ground wire, not shown)thus "shorting out" and completely discharging theelectroscope. Important: Place the electroscope asfar away from the cup as the wire permits. Next,charge up the glass rod and hold it far away fromboth the electroscope and the cup. Now bring theglass rod closer to the cup, but not too close. (Donot let the rod touch the cup, or you know whatmay happen to the gold foil.)

A charged plastic rod, when placed near a neutral, tiny, thin piece of paper, can pick up the paper. Which of the following is the best explanation for why this occurs? ANSWER O O O O O The piece of paper is a conductor, and charges of the opposite sign as the rod can move in the conductor closer to the rod. The paper actually had a slight charge to begin with, as nothing can exactly be neutral in nature. There are induced dipoles created in the paper from the presence of the nearby plastic rod. The described phenomenon is actually impossible, as a charged rod can't pick up a neutral piece of paper. I DON'T KNOW YET
I need the answers of a, c and g. Kindly solve it correctly. This questions are solved in wrong way previously. Follow the instructions given with the box.
Directions: Assume, unless otherwise specified, that all numbers have at least 3 significant figures. You may work together, but make sure that you are working--not just watching. The magnitude of the force of attraction between the proton and electron in a hydrogen atom is: F = where e is the magnitude of the charge, k is a constant, and r is the radius of the circular orbit. Assume the proton is fixed in place and the electron is in a circular orbit of radius ri. The electron then "jumps" to a new, smaller radius r2. What is the change in the total mechanical energy of the system (in terms ri, r2, e, and k)? Hint: Use dynamics to calculate the kinetic energy for the electron in the initial and final orbits, then calculate the potential energy in both orbits (you will need to develop an expression for the potential energy and remember the force is attractive). Do you know what form the change in mechanical energy takes?
please verify if all these are correct. thank you!

Three identical point charges, each of mass m=0.260 kg and charge q, hang from three strings as shown in the figure. The lengths of the left and right strings are each of length L=28.0 cm and make an angle of ?= 25.0o with the vertical as shown.On the pages you intend to submit for your work for this problem, draw a Free Body Diagram for the ball on the right. Use a straight-edge and be NEAT. (HINT: There should be TWO forces due to the two charges to the left of this charge. You can identify those TWO forces as FE1 and FE2 on the FBD. Be sure to identify the tension force (T) and mg as well. You need not include the gravitational attractions between the masses as they will be insignificant. Finally, show on the diagram where ? ends up with respect to the tension force (T) and break that tension force into components in the diagram. Only the tension force should need to be broken into components.Also on those work pages, use your Free Body Diagram and apply Newton's 2nd Law (ΣF=ma) to…
