Homework Statement
Four charges are placed on the corners of a rectangle. What is the resultant force on the positive charge (a = 1.4 m, b = 0.9 m, q = 2.7 × 10-9C)?
the rectangle has a charge
-q____-q
-q____+q on the 4 corners of the rectangle ant a line r from the +q to the -q...
So i am having trouble figuring out how to approach this problem
