A glass slab of volume 0.02m3 is subjected to a hydraulic pressure of 5×106N/m2. If the bulk modulus of glass is 3.7×101
Bulk modulus: B = −pΔVV. Rearrange: ΔVV = −pB = −5×1063.7×1010≈−1.35×10−4. Magnitude: 1.35×10−4. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 1.35×10−4. This satisfies dimensional consistency and physical conditions given, so option A is scientifically correct.
