When the charge enters the magnetic feld at an angle x , how the radius can be expressed as?
2. Relevant equations
Force of charge in a magentic field = qvbsinx
centripetal force = mv^2/r
3. The attempt at a solution
when i combined the two equations above, i got r=mv/qbsinx,
but the question i did said the radius is directly proportional to sinx. What i have done wrong?Hope someone can help me 🙂
