Consider a magnetic field in positive x-direction. A charged particle enters this field at an angle of 90 degrees with the field. What will be radius of the path traced by this particle?

\(\frac{mv}{2qB  }\) \(\frac{mv}{qB  }\) \(\frac{2mv}{2qB  }\) \(\frac{3mv}{2qB  }\)

\(\frac{mv}{qB  }\)

Radius : r = \(\frac{mv}{qB  }\)
