Two long parallel copper wires carry currents of $5\,A$ each in opposite directions. If the wires are separated by a distance of $0.5\,m$, then the force between the two wires is
  • A${10^{ - 5}}\,N,\,$ attractive
  • B${10^{ - 5}}\,N,\,$ repulsive
  • C$2 \times {10^{ - 5}}\,N,\,$ attractive
  • D$2 \times {10^{ - 5}}\,N,\,$ repulsive

    A mass spectrometer is a device which select particle of equal mass. An iron with electric charge $q > 0$ and mass $m$ starts at rest from a source $S$ and is accelerated through a potential difference $V$. It passes $\rho$ through a hole into a region of constant magnetic field $\vec B\,$ perpendicular to the plane of the paper as shown in the figure. The particle is deflected by the magnetic field and emerges through the bottom hole at a distance $d$ from the top hole. The mass of the particle is
