7) These are two-dimensional cross sections through the and a cube. Rank order, from largest to smallest,the eletric luses du oned spheres surfaces a to e three-dimensiOi closed spheres Physics 4B fluses . too, through ta) tb) 8) The electric field inside a conductor in electrostatic equilibrium is (A) unifom (B) zero. (C) radial. (D) symmetric 9) A proton is released from rest at point B, where the potential is O V. Afterward, the proton moves toward A with a steady speed. B)oves toward A with an increasing speed Cymoves D) moves toward C with an increasing speed E) remains at rest at EB -100 V OV 100v s toward C with a steady speed four pairs of large parallel conducting plates. The value of the ectric potential is given for each plate. Rank the pairs according to the magnitude of 10) The diagram shows the electric field between the plates, least to greatest. 60 ) 1,2,3,4 90 1,2,3,4 90b 4,3, 2, 1 2, 3, 1, 4 D) 12, 4, 1, 3 2, 4, 1Explanation / Answer
7: Flux will be same for all of the geometries in A,C,D, as Flux is just depending upon the charge enclosed bt the "Gaussian" surface.
And greater in B,E
Therefore order is
B=E>A=C=D
8.Electric field inside a conductor is zero in equilibrium.
for Intermediate state, if there exist some electric field inside the conductir, free Electrons will experience a force due to that field, will be alligned such that field is zero.
9. Proton is positive charged particle, it will be attracted to negative potential, therefore it moves towards A, speed will increase.
Say it reached in middle of both plates, potential is half, so Kinetic energy of proton must be there for conservation of energy.
Potential energy is changed to kinetic.
10.
Yes the potential difference is correctely written by you.
