Question

cheak the correctness of equation using dimensional analysis Sn=u+a/2(2n-1)​

Answer 1

Here is your Answer

Writing the dimensional formula of each of them, we get

L1 = LT-1 + LT-2[T]

L1 = LT-1 + LT-1

Since all the terms do not have the same dimensional formula, the equation is dimensionally not correct.
