* A device used to detect ionizing radiation consists of a thin positively charged wire surrounded by a concentric cylindrical conducting shell with an equal amount of negative charge on the outer shell. The length of the cylinder and the wire is 16 cm and the radius of the cylinder is of 1.4 cm. The wire at the center has negligible thickness. The electric field at the cylinders inner wall is 2.9 x 10* N/C A) Draw a diagram of the device labeling the direction of the electric field. B) Calculate the total charge on the central wire. C) Calculate the flux of electric field at the cylinders wall. D) If an electron were to become free at the outer cylinders wall, calculate the magnitude of acceleration the electron would initially experience
