Modulus of rigidity of a liquid

A

Non-zero constant

B

Infinite

C

Zero

D

Cannot be predicted

Text Solution

Verified by Experts

The correct Answer is:
B
(b) Elongation `Deltal=(FL)/(AY)therefore Deltal prop (1)/(A)` [F,L and Y are constant]
or `(A_(2))/(A_(1))=(Deltal_(1))/(Deltal_(2))` (Area of cross-section of second wire)
`implies A_(2)=A_(1)((0.1)/(0.05))=2A_(1)=2xx4=8 mm^(2)`
