A metal sphere of radius R , density ₁ moves with terminal velocity V₁ through a liquid of density . Another sphere of same radius but density ₂ - moves through same liquid. Its terminal velocity is V ₂ . The ratio V ₁: V ₂ is
Options
- A( ₂+ ): ( ₁- )
- B( ₁+ ): ( ₂- )
- C( ₂- ): ( ₁- )
- D( ₁- ): ( ₂- )
Correct answer
D. ( ₁- ): ( ₂- )
Step-by-step solution
Terminal velocity, v ₁= 2 9 ( ₁- ) R ^2 ~g Similarly, aligned & v₂= 2 9 ( ₂- ) R^2 g & v₁ v₂ = ( ₁- ) ( ₂- ) aligned
