Find theelectricfieldapplied on a system with electrons having a velocity 5m/s subjected to a magnetic flux of 3.6 units. Explanation: Theelectricfieldintensity is the product of the velocity and the magnetic flux density. Thus E = v x B, on substituting v = 5 and B = 3.6, we get E = 5 x 3.6 = 18 units.
