A singly charged positive ion moving at 4.6 * 10^5 leaves a circular track of radius 7.94 mm along a direction perpendicular to the 1.8 -T magnetic field of the bubble chamber. Compute the mass in atomic mass units of this ion, and, from that value, identify it.
A helium nucleus and a neon nucleus are separated by a distance of 3.0 nm. The charge of the helium nucleus is +2e while that of a neon nucleus is + 10e .Find the magnitude of the
