A charge of q = +6.60 x 107C is spread evenly on a thin metal disk of radius 0.160 m. Then a charge of q = -6.60 x 1073C is spread evenly on a second thin metal disk with the same radius located 0.05 m above the first disk. HINT (a) Calculate the charge density (in C/m ) on the first disk. 0000000816 x c/m2 (b) Find the magnitude of the electric field (in N/C) in between the two disks, neglecting edge effects and assuming uniform distributions of charge. -14700 N/CA proton is projected in the positive x direction into a region of uniform electric field E, = -6.40 x 10 N/C. The proton travels +7.10 cm through the field as it comes to rest. (a) Determine the acceleration of the proton. (Indicate the direction with the sign of your answer.) x = -6131736530000 m/s- (b) Determine the initial speed of the proton. (Indicate the direction with the sign of your answer.) Vox 8704600 * Mm/s (megameters per second) (c) Determine the time interval over which the proton comes to rest. 141,959,785.1 * ns (nanoseconds)A very large conducting plate lying in a horizontal plane carries a charge per unit area of -90 nC/m-. A second horizontal plate, located 6.00 cm above the first plate, carries a charge per unit area of 90 nC/m. Find the electric field in the following regions. (Indicate direction with the sign of your answer, where upward is the positive direction.) (a) below the first plate E = 5080 X N/C (b) in between the first and second plates E = 0 X N/C (c) above the second plate E = 5080 X N/C
