Asurface charge distribution is described by f=aoz s2 sin(o), where ao is a constant. find the total charge under the following conditions: a) the charge is distributed over the surface of a cylinder with radius 'r' and length 'l'. (the surface looks like a (unopened) coke can) b) the charge is distributed over the top and bottom surface of a wedge with radius 'r', height 'h', and circumference which is 1/8th the circumference of a circle with radius 'r'. (a 'wedge' looks like a slice of pizza. you can assume o starts at 0).

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
