The following charge distributions are present in free space: a point charge of 15 nC at P (2,0,6), a uniform line charge density of 5 nC/m at x = -2, y = 3, and an infinite uniform surface charge density of 0.1 nC/m^2 at x = 2.
1- Find the electric field at the origin.
2- Determine the force acting on a point charge of 6 C placed at the origin.
