The curve between charge density `rho` and distance r near `p - N` junction will be

The correct curve between potential (V) and distance (d) near p-n junction is.

A sphere of charges of radius R carries a positive charge whose volume chasrge density depends only on the distance r from the ball's centre as rho=rho_0(1-r/R), where rho_0 is constant. Assume epsilon as theh permittivity of space. the maximum electric field intensity is

A sphere of charges of radius R carries a positive charge whose volume chasrge density depends only on the distance r from the ball's centre as rho=rho_0(1-r/R), where rho_0 is constant. Assume epsilon as theh permittivity of space. the maximum electric field intensity is

A sphere of charges of radius R carries a positive charge whose volume charge density depends only on the distance r from the ball's centre as rho=rho_0(1-r/R) , where rho_0 is constant. Assume epsilon as theh permittivity of space. The magnitude of the electric field as a functiion of the distance r outside the balll is given by

A spherical region of space has a distribution of charge such that the volume charge density varies with the radial distance from the centre r as rho=rho_(0)r^(3),0<=r<=R where rho_(0) is a positive constant. The total charge Q on sphere is

A non-conducting spherical ball of radius R contains a spherically symmetric charge with volume charge density rho=kr^(2) where r is the distance form the centre of the ball and n is a constant what should be n such that the electric field inside the ball is directly proportional to square of distance from the centre?

What type of charges are left near and on either sides of the junction diode?
