A charge of 2.9 nC and a charge of 5.8 nC are separated by 40.80 cm. Find the equilibrium position for a -5.0 nC charge.

Hi Ace

Let A and B be the positon of 2.9 nC and 5.8 nC (A is on the left of B). Now put -5.0 nC on the left of A, between AB, and on the right of B. Draw electric forces acting on -5.0 nC at the three positions and find one that can make the resultant force on -5.0 nC becomes zero. Using the formula of electric force between two charges, find the position (distance from A or B)

Thanks, I tried it but i'm having no luck into fiding an accurate answer, Can i check mines? what did u get?

9.26 cm from A

EDIT : Actually I have another opinion but I just leave it for now. Can I know the answer from your manual?
