NEET Physics Shear Modulus MCQ Question
A square lead slab of side 50 cm and thickness 10 cm is subjected to a shearing force (on its narrow face) of 9 × 10⁴ N. The lower edge is riveted to the floor. How much will the upper edge be displaced? (Shear modulus of lead = 5.6 × 10⁹ N m⁻²)
0.16 mm
6 mm
0.16 cm
6 cm
Correct Answer
Detailed Explanation
The displacement is given by Δx = (F/A) / G * h. Calculating gives 0.16 mm.
