Two spheres made of different materials ...

Two spheres made of different materials have their masses in the rato of 1:2. If the diameter of the first sphere is equal to the radius of the second sphere, tehn determine the ratio dinsities volume of
sphere = `(4)/(3) pir^(3)`

Text Solution

Verified by Experts

Density = mass/volume
`d_1/d_2 = (m_1/v_1)/(m_2/v_2) = m_1/m_2 xx v_2/v_1 `
` = m_1/m_2 xx (4/3 pi r_2^3)/(4/3 pi r_1^3) = m_1/m_2 xx (r_2/r_1)^3`
` 4:1`
