detailed solution plz

Q1: A sphere of density 2500kg/m3 falls freely under gravity in a fluid of density 700kg/m3 and viscosity 0.0005kg/m.s a) Given that the terminal velocity of the sphere is 0.15m/s, calculate its diameter. b) What would be the side length of cube of the same material falling in the same fluid at the same terminal velocity?
