A galvanometer having a coil resistance \( 100 \Omega \) gives a full scale deflection when a current of \( 1 \mathrm{~mA} \) is passed through it. What is the value of the resistance which can convert this galvanometer into a voltmeter giving full scale deflection for a potential difference of \( 10 \mathrm{~V} \) ?
