proton and electron enters in magnetic field at an angle 30 degree .find the radius and time period in terms of magnetic field

  • physics -

    v(║) =vcosα
    v(┴)=vsinα

    m•v(┴)²/R=q•v(┴)•B•sin90º= q•v(┴)•B,
    R=mv(┴)/q•B.
    R(e)=m(e)•v(┴)/e•B.
    R(p)=m(p)•v(┴)/e•B.

    T(e)=2•π•R(e)/v(┴)
    T(p)=2•π•R(p)/v(┴)
