Which of the following statement is wrong?

A

Nuclear radius is often expressed in fremi `(1F = 10^(-15)m)`

B

Nuclear forces are short range and not strong attractive forces

C

Nuclear forces are about `10^(21)` times stronger than coulombic forces

D

Stabililty of nucleus is governed by inverse square law.

Text Solution

Verified by Experts

The correct Answer is:
`(d)`

Stablilty of nuclieus is governed by nuclear forces and not by inverse square law i.e, coulombic forces of attractions.
