NAME _____________________________________PHY 2049 Physics for Engineers and Scientists IIDr. J. B. BindellEXAMINATION #2INSTRUCTIONS: Be sure to write your name on the top of EVERY page of thisexamination because pages can be separated during the grading process. Answer eachquestion carefully and neatly so that it can be easily read and followed. Answers withoutbackup will be considered wrong even if the answer itself is correct. Show all work. Trynot to get hung up on a single problem. Answer the questions that you think youunderstand first and then return to complete the other problem(s). You may use the backof the page if you need it but be sure to mention this on the front! Good luck.Problem #1 (30):A wire of radius R has a non-uniform current density that is given by the expression:2ArJ .What is the TOTAL current flowing through the wire?122922120/Nm 109/C 1085.8CkNmNAME _____________________________________Problem #2 (35):Four capacitors are connected as shown in the Figure below. (a) Find the equivalent capacitance between points a and b. (b) Calculate the charge on each capacitor if ΔVab = 15.0 V. Vab=15 volts2NAME _____________________________________Problem 3 (35):Consider the array of charges shown in the diagram below.(a) Calculate the energy required to assemble the array of charges shown in the Figure if a = 0.200 m, b = 0.400 m, and q = 6.00 μC. (b) Consider the -2q particle in the upper right hand corner of the diagram. If it is suddenly released, calculate the maximum kinetic energy it will have if its mass is 2 x 10-6
