Volume of a sphere having its radius of r, V = (4/3)*¥ðr^3.

Letting the density and radius of Material 1 sphere as ¥ñ1 and r1 respectively, its mass M1 is:

M1 = ¥ñ1(4/3)*¥ðr1^3

Letting the density and mass of Material 2 sphere as ¥ñ2 and M2(=M1) respectively, its volume V2 is:

V2 = M1/¥ñ2 = ¥ñ1/¥ñ2 (4/3)*¥ðr1^3     = (4/3)*¥ðr2^3

Thus, r2 is:

r2 = r1*(¥ñ1/¥ñ2)^(1/3)


*** Âü°í¹®Çå[References] ***

r2 = r1*(¥ñ1/¥ñ2)^(1/3)
