Problem 5 (need to show coordinate system used in the calculation. Draw a clear picture (and label) showing the vectors of the blot savart law. 16 points A loop shaped in the form of a square, with sides of length 21, carries current I. 3) Using BiotSavart in full detail (vectors, cross product, limits of integration, vector addition}, nd the magnitude of the magnetic eld from the loop at a distance R from the center of the loop along a line that is perpendicular to the loop and goes through the center of the loop, as a function of l and L. (Use any variable or symbol stated above along with the following as necessary: [10}. Be clear about the limits of integration and about the direction of the magnetic field B for each side of the square (use vector notation}. '3] Calculate the total torque on the square loop in the case of a current of l=4Amps, 2L=5m id a magnetic eld B=(1,1,0.5}Teslas. Problem 3 (7 points) Consider the circuit shown below. What is the energy (in J} stored in each capacitor after the switch has been Elosed for a very longtime? R2 = 900 Q + ; V=16V R3=9000 C2=7.5mF
