6. A stream of charged particles, which could be either a or 3 particles, generates a radial [10] electric field with a field strength E = 10 V/m at a distance r = 2 cm from the axis. a) For the orientation of E as shown in the figure, is it a stream of a-particles (helium nuclei, i. e. 2 protons and 2 neutrons) or 3 particles (electrons)? b) What is the density of particles in the stream?
