An electric field is uniform and in the positive x direction for positive x and uniform with the same magnitude but in the negative x direction for negative x. It is given that E=200 hat(i) N//C for x gt 0 and E=-200 hat(i) N//C for x lt 0. A right circular cylinder of length 20 cm and radius 5 cm has its centre at the origin and its axis along the x-axis so that one face is at x=+10 cm and the other is at x=-10 cm What is the net charge inside the cylinder? |

Answer» Solution :The NET charge within the cylinder can be found by using Gauss's-law which GIVES `q=epsi_(0) phi` `=3.14xx8.854xx10^(-12) C` `=2.78xx10^(-11)C` |
