The mass of an ibon ball is 115g and its volume is 5cm3. Find its density in:i) C.G.S ii) S.I unit. PLEASE TELL THIS ANSWER ​

Answer»

Answer :-

(i) DENSITY in C.G.S unit = 23 g/cm³

(ii) Density in S.I. unit = 23000 kg/m³

Explanation :-

We have :-

→ Mass of the ball = 115 g

→ Volume = 5 cm³

To find :-

→ Density (In C.G.S and S.I. unit)

________________________________

Firstly, we have to calculate density of the IRON ball in C.G.S. unit. C.G.S. unit of density is g/cm³ . So, putting values in formula of density, we get :-

Density = Mass/Volume

⇒ Density = 115/5

⇒ Density = 23 g/cm³

Now, we have to calculate it's density in S.I unit . S.I. unit of density is kg/m³ . So, we have to just convert the answer obatined above in S.I. unit .

⇒ 1 g/cm³ = 1000 kg/m³

⇒ 23 g/cm³ = 23(1000) kg/m³

⇒ 23000 kg/m³
