Aspool rests on a horizontal, frictionless surface and you are looking at it from the top view (appears as a circle). in the following questions, the spool is pulled by tension forces that are applied at various locations, directions, and radii. to solve each problem, draw the spool as a circle on a piece of paper and then draw the given tension vectors. remember that the direction upward points to the top of the page and downward points to the bottom of the page. the resulting torque will be either out of the page (ccw motion, positive torque) or into the page (cw motion, negative torque).1)a rope of tension 2t applies a force at radius 1r on the spool. it is located at 9 o'clock and points downward. what is the resulting torque in terms of rt? remember to check whether the torque is positive (results in ccw motion) or negative (results in cw motion). 2.00 rt you are correct.2)a rope of tension 1t applies a force at radius 1r on the spool. it is located at 12 o'clock and points right. what is the resulting torque in terms of rt? -1.00 rt3)rope #1 of tension 1t applies a force at radius 4r on the spool. it is located at 12 o'clock and points right. rope #2 of tension 1t applies a force at radius 3r on the spool. it is located at 9 o'clock and points downward. what is the resulting torque due to both ropes in terms of rt?

Chapter 23, problem 075 the figure shows a geiger counter, a device used to detect ionizing radiation (radiation that causes ionization of atoms). the counter consists of a thin, positively charged central wire surrounded by a concentric, circular, conducting cylindrical shell with an equal negative charge. thus, a strong radial electric field is set up inside the shell. the shell contains a low-pressure inert gas. a particle of radiation entering the device through the shell wall ionizes a few of the gas atoms. the resulting free electrons (e) are drawn to the positive wire. however, the electric field is so intense that, between collisions with gas atoms, the free electrons gain energy sufficient to ionize these atoms also. more free electrons are thereby created, and the process is repeated until the electrons reach the wire. the resulting "avalanche" of electrons is collected by the wire, generating a signal that is used to record the passage of the original particle of radiation. suppose the radius of the central wire is 24 âµm, the inner radius of the shell 2.3 cm, and the length of the shell 14 cm. if the electric field at the shell's inner wall is 2.8 ă— 104 n/c, what is the total positive charge on the central wire?
