Question

Correctness of an equat ion T=2×pie roother of L/g dimensional

Answer 1

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.
