Question
A glass slab of volume 0.05m3 is subjected to a hydraulic pressure of 8×106N/m2. If the bulk modulus of glass is 3.7×1010N/m2, what is the fractional change in volume?
Explanation
Bulk modulus: B = −pΔVV. Rearrange: ΔVV = −pB = −8×1063.7×1010≈−2.16×10−4. Magnitude: 2.16×10−4. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 2.16×10−4. This satisfies dimensional consistency and physical conditions given, so option A is scientifically correct.
