Question: problern 3 the figure below shows an infinitely long conducting...

Question details

Problern 3. The Figure below shows an infinitely long conducting rod of radius R1 = 1 em. It is inside a coaxial conducting shell with radius R2-5 em. The net charge density (A) on the rod is -2.4 x 10-C/m while the outer coaxial conducting shell has a charge density (A2) of +7.2 x 109 C/m (a) Find the electric field at a distance of R 3 cm from the centre of this coaxial configuration. (b) Find the the electric field at a distance of R = 7 cm from the centre of this coaxial configuration
