(Given charge of a proton is 1.6 x 10-1°C). Assume one such alpha particle travels in a circular path of radius 20 cm in a uniform magnetic field of magnitude 1.25T. (i) What is the speed of the alpha particle ? (b) If an electron of (m=9.11x10-3'kg) travels with the same speed as of the alpha particle in the same magnetic field, (i) Calculate the radius of the circular path traced by the electron? (ii) Also, calculate the ratio of the radius of the electron to the radius of the alpha particle?
