My physics teacher gave us a problem about a charged particle; it was a theoretical problem, so there weren't any figures. He said that the charge of the particle, the value of the magnetic field, and the mass was known. Then he said that we needed to find the velocity of the charged particle. I am not sure how to do this! i used the formula: qvB=F and set that equal to ma=F. From this i got qvB=ma, however, I am not sure how to simplify the equation so that I am only solving for velocity in terms of q,B, and m! please help!
