Homework Statement
A particle with charge q and kinetic energy K travels in a uniform magnetic field of magnitude B. If the particle moves in a circular path of radius R, find expressions for speed, v, and mass, m.. (Use any variable or symbol stated above as necessary.)
Homework Equations
K=1/2mv^2 F=qvB=(mv^2)/R
The Attempt at a Solution
2K=mv^2 ---> qvB=(2K)/R ---> (2K)/(qBR)
Why is this incorrect?
