Arod 14.0 cm long is uniformly charged and has a total charge of -22.0 μc. determine the magnitude and direction of the net electric field produced by the charged rod at a point 36.0 cm to the right of its center along the axis of the rod.

Explanation:

It is given that,

Length of the rod, l = 14 cm = 0.14 m

Charge on the rod,

We need to find the magnitude and direction of the net electric field produced by the charged rod at a point 36.0 cm to the right of its center along the axis of the rod, z = 36 cm = 0.36 m

Electric field at the axis of the rod is given by :

Where

is the linear charge density of the rod,

E = -7493170.57 N/C

or

Negative sign shows that the electric field is acting in inwards direction. Hence, this is the required solution.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
