Q102 / 200 · NEET 2022 (Phase 2) · Physics

The physical quantity that has the same dimensional formula as pressure is:

  • A
    Force
  • B
    Momentum
  • Correct answer
    C
    Young's modulus of elasticity
  • D
    Coefficient of viscosity

Solution

Dimensions of Pressure $=\left[\mathrm{ML}^{-1} \mathrm{~T}^{-}\right.$ $\left.{ }^2\right]$ Dimension of Force $=\left[\mathrm{MLT}^{-2}\right]$ Dimension of Momentum $=\left[\mathrm{MLT}^{-1}\right]$ Dimension of Young's modulus of elasticity $=$ $\left[\mathrm{ML}^{-1} \mathrm{~T}^{-2}\right]$ Dimension of coefficient of viscosity $=\left[\mathrm{ML}^{-1} \mathrm{~T}^{-1}\right]$

Hence, the correct answer is option: 'C'.
