Q11. A galvanometer of resistance $100 \Omega$ when connected in series with $400 \Omega$ measures a voltage of upto 10 V . The value of resistance required to convert the galvanometer into ammeter to read upto 10 A is $x \times 10 ^ { - 2 } \Omega$. The value of $x$ is :\\
(1) 2\\
(2) 800\\
(3) 20\\
(4) 200
