The electric field `vecE=E_0yhatj` acts in the space in which a cylinder of radius r and length `l` is placed with its axis parallel to y-axis. The charge inside the volume of cylinder is:
| A. |
`E_0epsilon_0 l^2/2` |
| B. |
`E_0epsilon_0 pi r^2l^2` |
| C. |
`E_0epsilon_0 pi r^2l` |
 |
| D. |
`2E_0epsilon_0 pi r^2l` |
