Question

Please give the answer with good explanation!

Answer 1

Answer:

Let Tρrσ

Dimersim of T=[T] ρ is density

Dimersim of r=[L] r is radius

Dimersim of σ=[mT

−2

] σ is surface Tension

Dimersim of ρ=[mL

−3

] Then T

c

comparative on both sides

a−3c=0 12−2b

b+c=0

Solving =b=−1/2,c=1/2a=3/2

∴T=r
