A glass slab of volume 0.04m3 is subjected to a hydraulic pressure of 7×106N/m2. If the bulk modulus of glass is 3.7×101
Bulk modulus: B = −pΔVV. Rearrange: ΔVV = −pB = −7×1063.7×1010≈−1.89×10−4. Magnitude: 1.89×10−4. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 1.89×10−4. This satisfies dimensional consistency and physical conditions given, so option A is scientifically correct.
