If equation `int (dt)/(sqrt(3a - 2t^(2))) = a^(x) sin ^(-1) ((r^(2))/(a^(2)) - 1)`, the value of x isA. `(3)/(2) `B. `0`C. `(1)/(2)`D. `-(1)/(2)` |

Answer» Correct Answer - b `((t^(2))/(a^(2)) - 1)` is dimensionless ` :. [a] = [t]` As, `sqrt((3at - 2t^(2))) = [r]` `:. [(dt)/sqrt((3at - t^(2)))] = ([t])/([t])=[M^(0)L^(0)T^(0)]` `a^(2)` should be dimensionless so `x =0` |
