The drawing shows an equilateral triangle, each side of which has a length of \( 3.84 \mathrm{~cm} \). Point charges are fixed to each corner, as shown The \( 4.00 \mu \mathrm{C} \) charge experiences a net force due to the charges \( a_{A} \) and \( q_{\mathrm{B}} \). This net force points vertically downward and has a magnitude of \( 451 \mathrm{~N} \). Determine (a) charge \( q_{A} \), (b) charge \( q_{\mathrm{B}} \).
