If the mass time and work are taken as fundamental physical quantities then dimensional formula of lengthA. `[m^(1/2)T^(1)W^(-1/2)]`B. `[M^(-1/2)T^(1)W^(1/2)]`C. `[M^(-1)T^(2)W]`D. none of these |

Answer» Correct Answer - B `L=M^(a)T^(b)(ML^(2)T^(-2))^(c)` `a+c=0` ` 2c=1` `c=1/2 a= (-1)/2` ` b=2c=0 rArr b=1` |
