A galvanometer of resistance \( 100\,\Omega \) when connected in series with \( 400\,\Omega \) measures a voltage of up to \( 10\,\text{V} \). The value of resistance required to convert the galvanometer into ammeter to read up to \( 10\,\text{A} \) is \( x \times 10^{-2}\,\Omega \). The value of \( x \) is:
