A lead sphere of mass m falls in a viscous liquid with a terminal velocity v0. Another lead sphere of mass S m through the same liquid will fall with the terminal velocity: |
|
Answer» `v_(0)` `therefore` VOLUME is also 8 times the first sphere or radius is 2 times the first sphere. As TERMINAL velocity `V oo r^(2)`. `therefore` Velocity becomes 4 times`rArrv^(2)=4v_(0)` Thus correct choice is (b) Hence the correct choice is (c). |
