Important features (characteristics) of nuclear forces are given below (i) Nuclear forces are independent of charge. (ii) Nuclear forces are strongest in nature and are about 100 times stronger than electrostatic forces. (iii) The nuclear forces are very short range ...
For nuclei of high mass number, the number of protons inside the nucleus is more. These protons repel each other. Due to larger force of repulsion on account of greater number of protons present in the nucleus, the value of ...
Two distinguishing features of nuclear forces are as follows: (i) Nuclear forces are extremely short range forces. (ii) These are charge independent. Class 12 Physics Chapter 13 Nuclei Session 2024-2025.
Binding energy per nucleon of light nuclei is less and these are unstable. The binding energy per nucleon of the nucleus formed, as a result of fusion, is comparatively higher and nucleus is stable. Class 12 Physics Chapter 13 Nuclei ...
