Identify the physical quantity x defined as `x = (I F upsilon^2)/(W I^3),` where I is moment of inertia, F is force, `upsilon` is veloicty, W is work and I is length. |

Answer» As is known, `I = ML^2 , F= MLT^(-2), upsilon = LT^(-1)` `W = ML^2 T^(-2),l = L` `:. X =(Ifupsilon^3)/(WI^3) = ((ML^(2))(MLT^(-2))(LT^(-1))^(2))/((M^(1)L^(0)T^(-2))L^(3))` `= [M^1 L^0 T^(-2)]` These are the dimensions of surface tension or force constant or energy per unit area. |
