Consider points inside the sphere, r < R, which of the following statements best describes the behavior of the electric potential, V,inside the sphere: O The electric potential is a non zero constant everywhere inside the sphere O The electric potential is zero everywhere inside the sphere, O The electric potential is proportional to the distance from the center Ohe electric potential is inversely proportional to the distance squared O The electric potential is inversely proportional to the distance cubed from the center 31

Consider a parallel-plate capacitor made up of two conducting plates with dimensions 34 mm × 18 mm. a) If the separation between the plates is 1.1 mm, what is the capacitance, in pF, between them?  b) If there is 0.32 nC of charged stored on the positive plate, what is the potential, in volts, across the capacitor?  c) What is the magnitude of the electric field, in newtons per coulomb, inside this capacitor?  d) If the separation between the plates doubles, what will the electric field be if the charge is kept constant?

Where is the magnitude of the electric potential greatest? y A +2 R ' B 1 I
