Question

A fully ionized Helium ion (charge = +3.204*10^(-19) C and mass 6.647*10^(-27) kg) enters a uniform magnetic field of -1.34 T k (into the paper) with an initial velocity of (3.17*10^5 m/s) j, upward, as drawn at right. (A) Calculate the (vector) force on this ion when it first enters the field. (B) Calculate the radius of the path the ion follows while in this magnetic field. A complete solution starts from Newton's second law, but you can ignore the force of gravity. The only force that matters is the magnetic force.
