A rigid spherical particle undergoes free settling in a liquid of density 750 kg m-3 and viscosity 9.81×10-3 Pa s. Density of the particle is 3000 kg m-3 and the particle diameter is 2×10-4 m. Acceleration due to gravity is 9.81 m s-2. Assuming Stokes law to be valid, the terminal settling velocity (in m s-1) of the particle is
A
2×10-3
B
3×10-3
C
4×10-3
D
5×10-3

Correct : d
