The time dependence of a physical quantity `P` is given by `P = P_(0)e^(-alpha t^(2))` , where `alpha` is a constant and `t` is time . Then constant `alpha` is//hasA. `[T^(-1)]`B. `[T^(-2)]`C. `[T^(1)]`D. `[T^(2)]` |

Answer» Correct Answer - B `P = P_(0)e^(-alpha t^(2))` …………. `[alpha t^(2)]=[M^(@)L^(@)T^(@)]` `implies [alpha] = [T^(2)]` |
