If the size of a nucleus (in the range of 10^(-15)to 10^(-14)) is scaled up to the tip of a sharp pin, what roughly is the size of an atom ? Assume tip of the pin to be in the range 10^(-5) m to 10^(-4)m.

1.	If the size of a nucleus (in the range of 10^(-15)to 10^(-14)) is scaled up to the tip of a sharp pin, what roughly is the size of an atom ? Assume tip of the pin to be in the range 10^(-5) m to 10^(-4)m.
Answer» Solution :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 m and `10^(-4)m`. 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 1 m. Thus a nucleus in an atom is as small in size as the tip of a sharp pin placed at the centre of a SPHERE of radius about a metre long.
