Q. Two bodies of equal mass undergo elastic collision. If one was at rest initially, after collision

समान द्रव्यमान के दो पिंड लोचदार टकराव से गुजरते हैं। यदि कोई टक्कर के बाद शुरू में आराम की स्थिति में था

A
Both move at equal speed
दोनों समान गति से चलते हैं
B
One remains at rest
एक विश्राम में रहता है
C
Velocities are exchanged
वेगों का आदान-प्रदान होता है
D
Both move in opposite direction
दोनों विपरीत दिशा में चलते हैं

Explanation

In a head-on elastic collision between equal masses, and one is initially at rest:

  • The moving object transfers all its momentum to the other.

  • Velocities are exchanged.

The initially moving object comes to rest, and the stationary one moves with the original velocity.
