The correctness of equation can be checked using the principle of homogeneity in dimensions.Using this principle, check whether the equation f=2pisqrt(l/g) is dimensionally correct, where f - frequency, I - length and g - acceleration due to gravity. |
| Answer» Solution :`[f]=[M^0L^0T^-1],[L]=[M^0LT^0],[G]=[M^0LT^-2]` SINCE `[f]ne[SQRT(l/g)],` the equation is WRONG. | |
