A) same in all the three cases
B) maximum in P position
C) maximum in Q position
D) maximum in R position
Correct Answer: D
Solution :
\[\eta =\frac{F/A}{x/L}\,\,\,\Rightarrow \,\,x\,=\,\,\frac{L}{\eta }\,\,\times \,\,\frac{F}{A}\] If \[\eta \] and F are constant then \[x\propto \frac{L}{A}\] For maximum displacement area at which force applied should be minimum and vertical side should be maximum, this is given in the R position of rectangular block.You need to login to perform this action.
