SATHEE: Physics And Measurement Question 243

Physics And Measurement Question 243

Question: If $v = \frac{a}{t} + b t^{3}$ where $v =$ velocity and t is time The dimensional formula of a and b are

Options:

A) $[T], [T^{- 3}]$

B) $[L], [L T^{- 4}]$

C) $[T^{- 3}], [T]$

D) $[L T^{- 4}], [L]$

Show Answer

Answer:

Correct Answer: B

Solution:

[b] Dimensionally $v = \frac{a}{t} \Rightarrow a = L T^{- 1} \times T = L$ also dimensionally $v = b t^{3} \Rightarrow b = \frac{L T^{- 1}}{T^{3}} = L T^{- 4}$
