Two point charges are a small distance apart. a. Sketch the electric field lines for the two if one has a charge four times that of the other and both charges are positive.
b. Repeat for the case in which both charges are negative.

Explanation:

We know that, like charges repel and unlike charges attract each other.

IF one of the charge is four times that of the other and both charges are positive, the field lines is shown in figure (1).

Two negative charges attract each other, the field lines is shown in figure (2).

The net force between charges is given by :

Whre

k is the electrostatic constant

r is the distance between charges

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
