A long thin wooden cylindrical pipe of radius R, carrying a uniform surface charge density σ, is rotating about its axis with an angular velocity ω that increases slowly with time as ω=kt, k is constant. Which of the statements are correct for region inside the pipe?
A spherical charged conductor has a surface charge density σ. The electric field on its surface is E and electric potential of the conductor is V. Now the radius of the sphere is halved keeping the charge to be constant. The new values of electric field and potential would be
