Question

Two concentric conducting thin spherical shells A and B having radii r_A and r_B (r_B>r_A ) are charged to Q_A and -Q_B ( |Q_B |> |Q_A | ) . The electrical field along a line, (passing through the centre is)

Correct answer: 2

|Q_B |> |Q_A | (given). Inside the shell B , the potential is a constant and negative. But V_A inside r_A is positive and greater than that of B because r_A V_B , one gets the course 1 / r . At B , the negative potential is more therefore the potential line is still negative. (c) explains all these factors. Note: However the question asked is the field and the diagrams given are for the potential. This is an error. aligned & Resistance = potential difference current & = ML ^2 ~T ⁻³ ~A ⁻¹ ~A = [ ML ^2 ~T ⁻³ ~A ⁻² ]
