railway RRB ALP (CBT 1 + CBT 2 + CBAT) Mock Test Series 2025 (New) General Science Physics Units and Dimensional Formula
The distance covered by a particle in time 't' is given by \(s = at + bt^2\) where 'a' and 'b' are two constants. The dimensional formula of 'b' is:
1
\([M^0 \ L^1 \ T^{-2}]\)
2
\([M^0 \ L^2 \ T^{-1}]\)
3
\([M^0 \ L^1 \ T^{-1}]\)
4
\([M^0 \ L^2 \ T^{-2} ]\)
