Question

If the size of a nucleus (~- 10^-15m ) is scaled upto the tip of a sharp pin ( ~- 10^-5m ) , then what roughly is size of the atom?

Answer 1

If we increase the size of nucleus from 10^-15 to 10^-5 then it means that we are increasing the size by 10^10. so we shall hv to increase the size of atom by 10^10 so size of atom is 10^-10 now we increasing by 10^10 so 10^-10×10^10=10^(-10+10)=10^0=1 i.e. it will be 1 meter.

Answer 2

Answer: the size of a nucleus is in the range of 10^-15 m and 10^-14 m. The tip of a sharp pin is taken to be in the range of 10^-5 m and 10^ -4m . Thus we are scaling up by a factor of 10 ^10. An atom roughly of size 10^-10 m will be scaled up to a size of 1m
