MCQ
The quantities $A$ and $B$ are related by the relation, $m = A/B$, where $m$ is the linear density and $A$ is the force. The dimensions of $B$ are of
- APressure
- BWork
- ✓Latent heat
- DNone of the above
✓
Answer
Correct option: C.
Latent heat
c
(c) $m$ = linear density = mass per unit length = $\left[ {\frac{M}{L}} \right]$
(c) $m$ = linear density = mass per unit length = $\left[ {\frac{M}{L}} \right]$
$A= force =$ $[ML{T^{ - 2}}]\;$ [B]=$\frac{{[A]}}{{[m]}} = \frac{{[ML{T^{ - 2}}]}}{{[M{L^{ - 1}}]}}$$ = [{L^2}{T^{ - 2}}]$
This is same dimension as that of latent heat.
