Given below are two statements:
| Assertion (A): | The size of nuclei of various elements can be measured more accurately by performing Rutherford-type scattering experiments in which fast electrons, instead of \(\alpha-\)particles, bombard the target element. |
| Reason (R): | Higher energy \(\alpha-\)particles begin to get affected by the nuclear forces as they approach closer to the nucleus. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
