Best answer
प्रश्नानुसार `A=56`
नाभिक की त्रिज्या `R=R_(0)A^(1//3)=(1.2xx10^(-15))xx(56)^(1//3)`
`~~4.6xx10^(-15)` मीटर अथवा 4.6 फर्मी
नाभिक का घनत्व `rho=("नाभिक का द्रव्यमान"M)/("नाभिक का आयतन"V)`
यहां `M=55.82"amu"=55.85xx1.67xx10^(-27)` किग्रा
`:.V=4/3piR^(3)=4/3pi R_(0)^(3)A`
`=4/3xx3.14xx(4.6xx10^(-15)0)^(3) "मीटर"^(3)`
`:.rho=(55.85xx1.67xx10^(-27))/((4/3)xx3.14xx(1.2xx10^(-15))^(3))`
`=2.28xx10^(7) "किग्रा//मीटर"^(3)`
