Question

The density of material in CGS system of units is 4 g / cm 3 . In a system of units in which unit of lengths is 10 cm and unit of mass is 100 g , the value of density of material will beNEET 2011 (Mains)

TestHub · Accepted Answer

Mass, ​ M = d V d = L 3 M ​ d = 4 g / cm 3 ​ If unit of mass is 100 g and unit of distance is 10 cm . So, density y ​ = ( 10 10 ​ cm ) 3 4 ( 100 100 g ​ ) ​ = ( 10 1 ​ ) 3 ( 100 4 ​ ) ​ ⋅ ( 10 cm ) 3 ( 100 g ) ​ = 40 g cm − 3 ​ Aliter u 2 ​ ​ = u 1 ​ ( M 2 ​ M 1 ​ ​ ) ( L 2 ​ L 1 ​ ​ ) − 3 = 4 ( 100 1 ​ ) ( 10 1 ​ ) − 3 = 40 ​
