A stream of protons and electrons are shot horizontally (from the left edge of the page to the right) with a speed of 1.2 x 10^6 m/s. A magnetic field is oriented perpendicular to this motion (upward, out of the page) with a magnitude of 1.225 T. What is the radius of the curvature and the...

The entire question was in my first post. The difference between radium to radon is 88 -> 86 so would charge 1 be 2 and charge 2 be -2?

So i do not know what the alpha-particles charge is, but i can look up radon's charge right? EDIT So the alpha-particle's charge is the opposite of what radium loses?

Coulomb's law is F = k x ((force1 x force2)/r^2) Where k is 8.99 x 10^9 and r = distance between them which is 5 x 10^-11 I do not know how to get the force of each particle. Some more help would be appreciated!

Radium decomposes radioactively to form radon (atomic number 86, which is also the number of protons in the nucleus) by emitting an alpha-particle from its nucleus. The mass of an alpha-particle is 6.6404 x 10^-24 grams. What is the force of repulsion between the radon nucleus and the...
