Question

Two charges  and  are fixed 1 m apart, with the second one to the right. Find the magnitude and direction of the net force on a −2-nC charge when placed at the following locations: (a) halfway between the two (b) half a meter to the left of the  charge (c) half a meter above the  charge in a direction perpendicular to the line joining the two fixed charges

I drew the diagram and looked up some videos online to help with but I am just stuck and confused.

Answer 1

What kind of charges are 1m apart?

Are the two equal in magnitude ?

If not then what values?

Are the two of same sign?
