Question

A conducting sphere has a net charge of 5 mC distributed on its surface. 1 he electric potential on the surface of the conducting sphere relative to infinity is 20 V. What arc t e values of the electric field and the electric potential inside the conducting sphere? E = 20 N/C, V = 0. E = 0, V = 20 V. Neither E nor V can be determined since the radius of the sphere is unknown. The shape of equipotential surfaces in between two oppositely charge plates are planes perpendicular to the plates. planes parallel to the plates. curved surfaces surrounding the plates. The electric field inside two oppositely charged conducting plates is uniform. Which one the following figures correctly represents the equipotential lines between two large conducting plates? From the definition of potential, argue whether or not potential is a vector or scalar. From the definition of electric field, argue whether or not the electric field is a vector or scalar. Read the lab manual D-5 thoroughly.

Explanation / Answer

4)

inside the conducting sphere,the Electric field is zero,because all the charges resides only on the surface

and potential is same at each point inside the sphere and is equal to potential on the sphere

so the answer is b) E = 0 and V = 20 V

5) in between the oppositely charged plates ,there are planes perpendicular to the plates originated from positive plate and ends on the negative plate

so the answer is a)
