An Electron is constrained to move along the y-axis with a speed of 0.1 c( c is the speed of light ) in the presence of electronic wave , whose electric field  E→=30  sin(1.5×107t-5×10-2x)V/m. The maximum magnetic force experienced by the electron will be :( Given  C = 3×108 ms-1 and electron charge =1.6×10-19C )
