Questions
A liquid drop of density , radius r and surface tension S, oscillates with time period T. Then which of the following expressions for is correct?
detailed solution
Correct option is A
T∝ρa sb rc⇒T=ML-3aMT-2bLc⇒M0L0T1=Ma+bL-3a+cT-2b-2b=1⇒b=-12a+b=0⇒a=12-3a+c=0⇒c=32∴T∝ρ1/2 s-(1/2) r3/2⇒T2∝ρr3sTalk to our academic expert!
