An infinitely long tube of semicircular cross section is given some electric charge One half of the tube is given a surface charge density o and the other half of o If lol 2 e coul m2 find the magnitude of electric field at point O on the axis The point 0 is some where near the centre on the axial line in volt m Given R 0 25 m D 0
