Question

A spherical ball contracts in volume by 0.02% when subjected to a pressure of 100 atmosphere. Assuming one atmosphere = 10⁵ Nm⁻², the bulk modulus of the material of the ball is:

Options

• 0.02 × 10⁵ N/m²

• 0.02 × 10⁷ N/m²

• 50 × 10⁷ N/m²

• 50 × 10⁹ N/m²

Answer 1

50 × 10⁹ N/m²

Explanation:

B = `-(Δ"P")/(Δ"V"//"V")`

= `(100 xx 10^5)/((0.02//100))`

= 50 × 10⁹ N/m²
