Please answer the following 5 questions with work, thank you!

Problem 1: Consider a conducting hollow cylinder. On the walls of the cylinder there is a uniform surface density of electric current g (see Figure 1). A conducting wire crosses the cylinder transversely. There is an electric current I in the wire. You are asked to calculate the absolute value of the magnetic field at a distance h from the wire at the point shown in Figure 1, which is on the axis of symmetry of the cylinder. Option A: 106 T Option B: 3 x 10-3 T Option C: 9 x 102 T Option D: 3.33 x 104 T Problem 2: Consider two electrically charged particles moving as shown in Figure 2. You are asked to calculate the velocity v such that the magnetic force that the two particles exert on each other is one quarter (1/4) of the electric force that the two particles exert on each other. Option A: 300,000.00 km/s Option B: 149,896.23 km/s Option C: 23,333.33 km/s Option D: 122.22 km/s Problem 3: Specify which of the configurations shown in Figure 3 satisfy the "action and reaction" law, Option A: a, b, d Option B: a, b, d Option C: a, b, c Option D: c, d Problem 4: Consider a capacitor like the one shown in Figure 4.

Option A: 88.121 mF Option B: 12.126 F Option C: 3.22 x 10-2 F Option D: 0.265 nF b) Now, suppose that the two dielectric materials are removed and the space between the plates is left empty. Calculate the capacity in that case. Option A: 88.54 10-12 F Option B: 0 Option C: 12.126 x 106 F Option D: 3.22 x 10-2 F Problem 5: Consider the circuit in the figure. a) Calculate the current I.
