Question
Which of the following equations is dimensionally inconsistent?
Explanation
(a) [s] = [L], [u t] = [L T^{-1] [T] = [L], consistent. (b) [v] = [L T^{-1], [a t] = [L T^{-2] [T] = [L T^{-1], consistent. (c) [F] = [M L T^{-2], [m v / t] = [M L T^{-1] / [T] = [M L T^{-2], consistent. (d) [E] = [M L² T^{-2], [m v t] = [M L T^{-1] [T] = [M L Tâ°], inconsistent.
