Barn is used to measure the cross-sectional area of the mucles of an atom. IT is equal to

A

`10^(-28) m^(2)`

B

`10^(-25) m^(2)`

C

`10^(-31) m^(2)`

D

`10^(-17) m^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Barn is the unit of area for measurring the cross-section of nuclei. 1 barn equals `10^(-24) cm^(2)` or `10^(-28) m^(2)`.
