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
• B. 1000 new units
• C. 1500 new units
• D. 2000 new units

Answer 1

The correct option is A 500 new units

Pressure $=\frac{kg{m}^1}{m^2{s}^2}=M^1{L}^{-1}{T}^{-2}$
$P_1=10Pa,P_2=\frac{10}{5}\times \frac{1}{(10{)}^2}$
$\Rightarrow \frac{P_1}{P_2}=\frac{10}{\frac{10}{5\times (10{)}^2}}=500$ new units
