Do you want to have an idea of how small a nucleus is? Let's try finding the nuclear radius of 12560X.
The value of R0 is 1.1×10−15SI units.
Ans: __________________ X 10−15m
R=R0A13, where A is the mass number.
Here the element that is given is 12560X
So its mass number is 125.
R=R0×12513R=1.1×10−15×5 m=5.5×10−15m
