Match List - I with List - II. List - I List - II a Torque i MLT - 1 b Impulse ii MT - 2 c Tension iii ML 2 T - 2 d Surface Tension iv MLT - 2 Choose the most appropriate answer from the option given below :
Options
- A(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
- B(a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
- C(a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)
- D(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
Correct answer
B. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
Step-by-step solution
The torque is defined as, τ = ⊥ r F sin θ = ML 2 T - 2 , the formula of impulse, I = ∆ p = MLT - 1 and tension, T = MLT - 2 and the formula of surface tension is defined as force per unit length. s = F l = M L T - 2 L = M T - 2 .
