A solid sphere has a radius of 2 cm and a mas of 0.05 kg. What is the relative density of the sphere ?

Text Solution

Verified by Experts

Raduis ot the = 2 cm
Volume of the sphere `=(4)/(3)pi^(3)=(4)/(3)xx(22)/(7)xx2xx2xx2=33.52cm^(3)`
`"Mass of the sphere"=0.05kg=50gm`
`"Density of the sphere"=("Mass")/("Volume")=(50)/(33.52)=1.49gm//cm^(3)`
`"Relative density"=("Density of the sphere")/("Density of water")=(1.49gm//cm^(3))/(1gm//cm^(3))=1.49`
