Question

In a new system, unit of mass is 10kg, unit of length is 5m and unit of time is 10s. Then 10 Pa $$=$$


A
500 new units
loader
B
1000 new units
loader
C
1500 new units
loader
D
2000 new units
loader

Solution

The correct option is A 500 new units
Pressure $$= \dfrac{kg m^{1}}{m^{2}s^{2}}=M^{1}L^{-1}T^{-2}$$
$$\displaystyle P_{1}=10 Pa  ,  P_{2}=\frac{10}{5}\times \frac{1}{(10)^{2}}$$
$$\displaystyle \Rightarrow \frac{P_{1}}{P_{2}}=\frac{10}{\dfrac{10}{5\times (10)^{2}}}=500$$ new units
