A charge of 3.00 C is located at the top location a distance d = 11 mm, a 2.50 C located at the origin and 2.00 C located to the right along x-axis a distance d = 12.2 mm. Calculate a) the diagonal line of the arrangement, then b) imagine a reference point P along that line a distance of 16.00 mm and calculate the force at that point, c) calculate the E-field at that point P d) the AV at the same point. y d
