A beam of well collimated cathode rays travelling with a speed of `5xx10^(6)ms^(-1)` enter a region of mutually perpendicular electric and magnetic fields and emerge undeviated from this region. If `|B|=0.02t`, the magnitude of the electric field is

Mutually perpendicular electric and magnetic fields are given by E = 1500 V/m and B = 0.04 T . Then velocity is given by
