Moving Charges and Magnetism

Question: A beam of well collimated cathode rays travelling with a speed of $5 \times {10^6}\,m{s^{ - 1}}$ enter a region of mutually perpendicular electric and magnetic fields and emerge undeviated from this region. If .., the magnitude of the electric field is


1) ${10^5}\,V{m^{ - 1}}$
2) $2.5 \times {10^8}\,V{m^{ - 1}}$
3) $1.25 \times {10^{10}}\,V{m^{ - 1}}$
4) $2 \times {10^3}\,V{m^{ - 1}}$
Solution: Explanation: No Explanation
Motion of Charged Particle In Magnetic Field
