Q.

Match List I with List II.

  List I   List II
A. Angular momentum I. [ML2T–2]
B. Torque II. [ML–2T–2]
C. Stress III. [ML2T–1]
D. Pressure gradient IV. [ML–1T–2]

Choose the correct answer from the options given below:          [2023]

1 A – I, B – IV, C – III, D – II  
2 A – III, B – I, C – IV, D – II  
3 A – II, B – III, C – IV, D – I  
4 A – IV, B – II, C – I, D – III  

Ans.

(2)

L¯=r→×p→ ⇒ [L]=[M0L1T0][M1L1T–1]=[M1L2T–1]

τ¯=r→×F→ ⇒ [τ]=[L1][MLT–2]=[ML2T–2]

Stress ≡ Pressure = FA ⇒ [Stress]=[ML–1T–2]

Pressure Gradient = dPdx

⇒ [Pressure Gradient] = [ML–1T–2]
