If the terminal speed of a sphere of gold (density = $19.5 \; kg/m^3$) is $0.2 \; m/s$ in a viscous liquid (density = $1.5\; kg/m^3$), find the terminal speed of a sphere of silver (density = $10.5 \; kg/m^3$) of the same size in the same liquid.

Question

( A ) 0.1 m/s
( B ) 0.4 m/s
( C ) 0.133 m/s
( D ) 0.2 m/s
