Question

As shown in the figure, forces of $10^5\, N$ each are applied in opposite directions, on the upper and lower faces of a cube of side $10\, cm$, shifting the upper face parallel to itself by $0.5 \,cm$. If the side of another cube of the same material is $20\, cm$, then under similar conditions as above, the displacement will be :

• A. 0.25 cm
• B. 0.37 cm
• C. 0.75 cm
• D. 1.00 cm

Answer 1

Answer: (A)

0.25 cm

Answer 2

Given: Force applied $F=10^{3} \,N ;$
side of cube $x=10 m =10 \times 10^{-2} \,m ;$
shift $d x=0.5 cm =0.5 \times 10^{-2}\, m$
