155625 In Thomson's experiment to determine $\frac{\mathrm{e}}{\mathrm{m}}$ of an electron, it is found that an electron beam having a kinetic energy of $45.5 \mathrm{eV}$ remains unelected, when subjected to crossed electric and magnetic fields. If $\mathrm{E}=1 \times 10^{3} \mathrm{Vm}^{-1}$, the value of $B$ is (mass of the electron is $9.1 \times 1^{-31}$ kg)
