The resistance of a galvanometer is $50\, ohms$ and the current required to give full scale deflection is $100\,\mu A$. In order to convert it into an ammeter, reading upto $10\,A$, it is necessary to put a resistance of
  • A$5 \times {10^{ - 3}}\,\Omega $ in parallel
  • B$5 \times {10^{ - 4}}\,\Omega $ in parallel
  • C${10^5}\,\Omega $ in series
  • D$99,950\,\Omega $ in series

    Consider the motion of a positive point charge in a region where there are simultaneous uniform electric and magnetic fields $\vec{E}=E_0 \hat{j}$ and $\vec{B}=B_0 \hat{j}$. At time $t=0$, this charge has velocity $\nabla$ in the $x$-y plane, making an angle $\theta$ with $x$-axis. Which of the following option$(s)$ is(are) correct for time $t>0$ ?

    $(A)$ If $\theta=0^{\circ}$, the charge moves in a circular path in the $x-z$ plane.

    $(B)$ If $\theta=0^{\circ}$, the charge undergoes helical motion with constant pitch along the $y$-axis.

    $(C)$ If $\theta=10^{\circ}$, the charge undergoes helical motion with its pitch increasing with time, along the $y$-axis.

    $(D)$ If $\theta=90^{\circ}$, the charge undergoes linear but accelerated motion along the $y$-axis.
