Modulus of rigidity of a liquidA. Non-zero constantB. InfiniteC. ZeroD

1.	Modulus of rigidity of a liquidA. Non-zero constantB. InfiniteC. ZeroD. Cannot be predicted
Answer» Correct Answer - 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)`
