Q6. A spherical ball of radius $1 \times 10 ^ { - 4 } \mathrm {~m}$ and density $10 ^ { 5 } \mathrm {~kg} / \mathrm { m } ^ { 3 }$ falls freely under gravity through a distance $h$ before entering a tank of water, If after entering in water the velocity of the ball does not change, then the value of $h$ is approximately: (The coefficient of viscosity of water is $9.8 \times 10 ^ { - 6 } \mathrm {~N} \mathrm {~s} / \mathrm { m } ^ { 2 }$ )\\
