Correctness of an equat ion T=2×pie roother of L/g dimensional |
|
Answer» Explanation: 2 and pie are DIMENSIONLESS. therefore √l/G should match the dimensions of 'T'. 'g' has dimension 'LT^-2' therefore √l/g will have dimensions √L/LT^-2 = √T^2 which is EQUAL to T. as dimension of LHS is equal to dimension of RHS, HENCE proved. |
