A sphere of radius R has a volume density of charge p=kr where r distance from the centre of the sphere and k is constant the magnitude of the electric field which exist at the surface of the sphere is given by (epsilon eo=permittivity of free space a)4πkR'4/3eo b)kR/3eo c) 4πkR/eo d) kR'2/4eo

Question

chetan jangir · Answer

Hi dear, Answer must be D. Calculate the within sphere that from center to disatnce R and then apply formula E=kq/r^2

Yashraj · Answer

assume a elemental hollow sphere and calculate the total charge which will be kR 4 and apply guass law assuming spherical urface of radius r around sphere nice question the game is integration
