In the equation

{S_{nth}}

the

= u + \frac{a}{2}\left( {2n - 1} \right),

the letters have their usual meanings. The dimensional formula of

{S_{nth}}

View answer and explanation

Correct option: C

\left[ {{\mathrm{M}^0}\mathrm{L}{\mathrm{T}^{ - 1}}} \right]

Option C ([

{\mathrm{M}^0}\mathrm{L}{\mathrm{T}^{ - 1}}}

]) is correct because

{S_{nth}}

represents distance covered in nth second, which is velocity, hence [LT⁻¹].
