कोष्टकात दिल्याप्रमाणे घनता असणाऱ्या सोन्यापासून आणि तांब्यापासून जर 0.50 kg. च्या समान वजनाचे दोन गोळे (चेंडू) बनवले तर / According to densities given in the table, if we prepare two spheres out of Gold and Copper each of a similar weight of 0.50 kg., then (सारणीतील घनता / Densities from the table: सोने / Gold = 19.30 g/cm³, तांबे / Copper = 8.96 g/cm³.)

1)सोन्याचा गोळा तांब्याहून मोठा असेल / The Golden sphere will be bigger than copper

2)सोन्याचा गोळा तांब्याहून लहान असेल / The Golden sphere will be smaller than copper✓ Correct

3)दोनों गोळे आकाराने समानच होतील / Both the spheres will be of same size

4)सोन्याचा गोळा तांब्याच्या तुलनेत बरोबर 19.30/8.96 एवढ्या आकाराचा होईल. / Golden sphere will be exactly 19.30/8.96 times than copper.

Density equals mass divided by volume (Density = Mass / Volume). Since gold has a much higher density than copper, for the same mass (0.50 kg), gold will occupy less volume, meaning the golden sphere is smaller.
