A light beam travelling in the x - direction is described by the electric field \[{{E}_{y}}=300\sin \] \[\omega \left( t-\frac{x}{c} \right)\]. An electron is constrained to move along the y - direction with a speed of \[2.0\times {{10}^{7}}m/s.\] Find the maximum electric force (in newton) on the electron.

Answer:

\[(4.8\times {{10}^{-7}})\]
