please help with questions 1,2,3,4,5,6,7,8,9,10,11,12,13, and 14 3. State both the sign and magnitude of thecharge on a proton, an electron, and a neutronin terms of e, the elementary charge.11. The diagram below shows the initial charges andpositions of three identical metal spheres, X, Y,and Z, which have been placed on insulatingstands. All three spheres are simultaneouslybrought into contact with each other and thenreturned to their original positions.4. The diagram below represents two electricallycharged identical-sized metal spheres, A and B.B.+2 µC+4 µC+6 μ+2.0 x 10-7 C+1.0 x 10-7 CIf the spheres are brought into contact, whichsphere will have a net gain of electrons?(3) both A and B(4) neither A nor B(1) A, only(2) B, only5. A small, uncharged metal sphere is placed near alarge, negatively charged sphere. Which dia-gram best represents the charge distribution ofthe smaller sphere?Which statement best describes the chargeof the spheres after this procedure iscompleted?(1) All the spheres are neutral.(2) Each sphere has a net charge of +4 µC.(3) Each sphere retains the same charge that ithad originally.(4) Sphere Y has a greater charge than sphere Xor sphere Z.(3)12. Two oppositely charged metal spheres arebrought toward each other.
