Statement 1: |
The centre of mass of an electron and proton, when released moves faster towards proton |
|
Statement 2: |
Proton is heavier than electron |

(d) The position of centre of mass of electron and proton remains at rest. As their motion is due to internal force of electrostatic attraction, which is conservative force. No external force is acting on the two particles, therefore centre of mass remain at rest |
