Expert Answer
Check dimensional correctness of
1/2 mv2 = mgh
Solution :-
L.H.S = 1/2 mv2
Dimension of m is [M]
Dimension of v is [ LT-1]
Thus, dimension of v2 is [L2T-2]
Thus, dimension of LHS is = [ML2T-2] ....(1)
RHS = mgh
Dimension of m is [M]
Dimension of g = [LT-2]
Dimension of h = [L]
Thus, dimension of RHS = [ML2T-2] .....(2)
Thus, from (1) and (2),
LHS =RHS
Hence, the given equation is dimensionally correct.
