Which of the following is the correct representation of Electric Field Lines with respect to conductors?
Question 3
Consider a charged spherical conductor, such that the charge per unit area on its surface is σ. If the electric field is E and the electric potential is V. Then the value of the electric field and potential would be if the radius of the sphere is reduced to (1/3) keeping the surface charge density same
Question 4
Which of the following is not true about electric field lines?
Question 5
