The velocity v of a particle at time t is given by v = at + b/(t + c), where a, b and c are constants, The dimensions of a, b and c are respectively :
Answer & explanation
Correct answer: option 1
\(v = at + \frac{b}{t + c}\)
⇒ [c] [t] = T
[v] = [at] ⇒ [a] = \(\frac{[v]}{[t]}\) = LT –2
[b] = [LT–1] T = L
