Answer» A proton projected in a magnetic field of <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $0.02 T$ moves along a helical path of radius <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $5 cm$ and pitch <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> $20 cm$ . Find the componet of velocity parallel to the magnetic field. Take the mass of the proton $1.6 \times 10^{- 27} kg$
