6. There is a hollow region between r and R. It is filled with a uniform charge density of 80 nC/m3. r =1.0 mm (shown below) and the outer radius R = 3.0 mm. Determine the magnitude of the electric field at a point which is 2.0 mm from the symmetry axis.Given In question Charge density p - 80n 4 radius of cylinders =l x 10 m ro = 3 x 10 'm to find the electric at a point 2mm form axis The linear charge density is given by =80 x 10 " x 1 14 x (8 x 10 * ] m The electric field at 2mm distance from symmetry axis is given by 2 x 10-1 2x314 x2 x 10- N
