11. Assume the pupil diameter is 0.50 cm and n = 1.22 for the naked eye. What is the maximal distance if one is to distinguish between two blue lights (\( \lambda = 500 \) nm) separated by 1.5 m? (A)6.0 km (B)12 km (C)9.0 km (D)3.0 km (E)15 km

9. In the right figure, \( R_1 = 5\Omega \), \( R_2 = 10\Omega \), \( R_3 = 15\Omega \), \( C_1 = 5\mu F \), \( C_2 = 10\mu F \), and the ideal battery has an emf \( \varepsilon = 20V \). In steady state, the total energy stored in the two capacitors is: (A)\( 2.78\times10^{-5} \) J (B)\( 1.12\times10^{-4} \) J (C)\( 2.22\times10^{-4} \) J (D)\( 2.50\times10^{-4} \) J (E)\( 4.72\times10^{-4} \) J
