Physics And Measurement Question 67
Question: The quantities $ A $ and $ \times $ are related by the relation, $ [ML{{T}^{-1}}] $ , where $ m $ is the linear density and $ A $ is the force. The dimensions of $ B $ are of
Options:
A) Pressure
B) Work
C) Latent heat
D) None of the above
Show Answer
Answer:
Correct Answer: C
Solution:
$ m $ = linear density = mass per unit length = $ [ \frac{M}{L} ] $
A= force = $ [ML{{T}^{-2}}]\ $ [B]= $ \frac{[A]}{[m]}=\frac{[ML{{T}^{-2}}]}{[M{{L}^{-1}}]} $
$ =[L^{2}{{T}^{-2}}] $ This is same dimension as that of latent heat.
