A light beam travelling in the

x

-direction is described by the electric field

E_y=(300\,\mathrm{V\,m^{-1}})\sin\omega(t-x/c)

. An electron is constrained to move along the

y

-direction with a speed of

2.0\times10^7\,\mathrm{m\,s^{-1}}

. Find the maximum electric force and the maximum magnetic force on the electron.
