सूची$-I$ को सूची$-II$ से सुमेलित कीजिए।
| सूची$-I$ | सूची$-II$ |
| $(a)$ बल आघूर्ण | $(i)$ ${MLT}^{-1}$ |
| $(b)$ आवेश | $(ii)$ ${MT}^{-2}$ |
| $(c)$ तनाव | $(iii)$ ${ML}^{2} {T}^{-2}$ |
| $(d)$ पष्ठ तनाव | $(iv)$ ${ML} {T}^{-2}$ |
A$(a)-(iii), (b) -(i), (c)-(iv), (d)-(ii)$
B$(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)$
C$(a)-(i), (b)-(iii), (c)-(iv), (d)-(ii)$
D$(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)$
(JEE MAIN-2021)
Solution
torque $\tau \rightarrow {ML}^{2} {T}^{-2}$ $(III)$
Impulse $I$ $\Rightarrow {MLT}^{-1}$ $(I)$
Tension force $\Rightarrow {MLT}^{-2}$ $(IV)$
Surface tension $\Rightarrow {MT}^{-2}$ $(II)$
Impulse $I$ $\Rightarrow {MLT}^{-1}$ $(I)$
Tension force $\Rightarrow {MLT}^{-2}$ $(IV)$
Surface tension $\Rightarrow {MT}^{-2}$ $(II)$
