Four metal spheres, each 1cm in diameter are arranged on an X-Y coordinate plane as follows:
Sphere 1 has a charge of +2 millicoulombs and is situated at coordinate (0,0)
Sphere 2 has a charge of +3 millicoulombs and is situated at coordinate (0.-4 cm)
Sphere 3 has a charge of -4 millicoulombs and is situated at coordinate (-3 cm,0)
Find the resultant force in Newtons on a fourth sphere with a charge of +1 millicoulomb situated at coordinate (4 cm, 4 cm).
