An electron is moving at \(\rm 5 \ km/s\) along \(\rm {\hat a_y}\) in a magnetic field, the magnetic flux density is given by \(\rm 2{\hat a_x} + 3{\hat a_y} + 4{\hat a_z}\ Wb/{m^2}\). What is the electric field intensity?
1
\(\rm 20{\hat a_x} - 10{\hat a_z}\)
2
\(\rm - 30{\hat a_x} - 40{\hat a_z}\)
3
\(\rm - 20{\hat a_x} + 10{\hat a_z}\)
4
\(\rm 30{\hat a_x} + 40{\hat a_z}\)
