Question

A particle at rest suddenly disintegrates into two particles of equal masses which start moving. The two fragments will (A) Move in the same direction with equal speeds (B) Move in any directions with any speed (C) Move in opposite directions with equal speeds (D) Move in opposite directions with unequal speeds

A particle at rest suddenly disintegrates into two particles of equal masses which start moving. The two fragments will move in opposite directions with equal speeds (From momentum conservation).

Q. A particle at rest suddenly disintegrates into two particles of equal masses which start moving. The two fragments will

Move in the same direction with equal speeds

Move in any directions with any speed

Move in opposite directions with equal speeds

Move in opposite directions with unequal speeds

A particle at rest suddenly disintegrates into two particles of equal masses which start moving. The two fragments will move in opposite directions with equal speeds (From momentum conservation).
