Two positively charged spheres are placed at positions A and B as shown below. At point \( P \) the net electric field \( \left(E_{\text {net }}\right. \) ) is \( 2.00 \mathrm{~N} / \mathrm{C} \) at \( 71.3^{\circ} \mathrm{N} \) of \( \mathrm{E} \). The charge on object \( B \) is c. \( 8.43 \times 10^{-10} \) \( 1.43 \times 10^{-10} \) \( 8.90 \times 10^{-10} \) \( 2.85 \times 10^{-10} \)
