An infinite line charge lambda is located along the z-axis. A particle of mass m that carries a
charge q whose sign Is opposite to that of lambda is in a circular orbit in the xy plane about the
line charge. Obtain an expression for the period T of the orbit in terms of m. q. R, and lambda,
where R is the radius of the orbit.
Solution
m*R*2 =| ( /20R) * q |
= 2/T
therefore
T = sqrt ( (2)3 * m *0 * R2 / |q| )
