A:- d relation 4 disp. covered in n^th sec. by a
uniformly acc. particle -
s = u + a/2[2n-1] is dimensinaly corect.
R:- 1 sec. is coeficient of both terms on RHS.

hey i could nt understand the question
i just sought out and say that s=u+1/2a(2t-1) is dimensionally incorrect

well it was a MCQ there and not AR 
well try to derive it
and u'll find y it seems dim incorrect

u can check out solutions--its clearly specified..
neways easier method...u can multiply both LHS and RHS by "t"
and then put t=1 in LHS (since we r taking of nth sec)
that wud make it dim correct...

The answer is (1) acc. to me b/c on the rhs,both the terms give the dimensions of displacement if we multiply them by 1sec- u x t(=1) and a t(squared) (t=1) so....its dimentionally correct... It is for the nth sectond so t=1...it is similar to s=ut+1/2 at(squared)
