3 Charged Closed Wire Consider a thin closed wire with the radius R localized at the origin on the xy-plane, which is charged uniformly with the total charge Q. (i) What is the charge density p in this problem? (ii) Calculate the electric field along the z axis? (Hint: First, consider an infinitessimal piece of the charge.)

Please show all work ง 5. Evaluate the vector surface integral JJ (+2², x + 2y + 32², 5x − 2y + 2³) . Ndo. S Here, S is the sphere Sy²+2 1. = Since S is a closed surface, the outside of S is considered as the positive side on S. Hint: use the divergence theorem.

Problem 4. (20 points) Consider a LTV system (t) = A(t)x(t) where x(t) = R² and === 3 A(t) == -2-6t 4+8t] -1-2t 2+2t -2 4 = +2t. -1 2 A1 A2 Vt ≥ 0. ' Note that A₁ is the exact same state dynamics matrix in Problem 3 (hence A² = 0) and A₂ = A₁-I. Find the fundamental matrix (t), namely, the state transition matrix (t,0), of the system.
