The drawing shows an equilateral triangle, each side of which has a length of 1.59 cm. Point charges are fixed to each corner, as shown. The 4.00 C charge experiences a net force due to the charges qA and qB. This net force points vertically downward and has a magnitude of 488 N. Determine
(a) charge qA,
(b) charge q
