Please be detailed. Im having issues figuring out why and when some of the components are negative, and how to use the formula F=qE to interchange between Electric Force and Electric Field. My answers just doesnt match. I have a test monday and I cant figure this out. Thanks!

Explanation / Answer

Three point charges are located at the corners of an equilateral triangle as shown in Figure P23.7. Calculate the net electric force on the 7.00?
