Question

Forces of 100 N each are applied in opposite
direction on the upper and lower faces of a cube of
side 20 cm. The upper face is shifted parallel to
itself by 0.25 cm. If the side of the cube were 10
cm, then the displacement would be
(a) 0.25 cm
(b) 0.5 cm
(c) 0.75 cm
(d) 1 cm​

Answer 1

Answer:

Option b

hope its help you

Answer 2

Explanation:

η=FlA△l=Fll2△l=F<ri∠l  or △l∝1l

If l is halved, then △l is doubled.
