A hand cart loaded with vegetables collides with an identical but empty hand cart. During the collision:
(i) the loaded cart exerts a force of larger magnitude on the empty cart.
(ii) the empty cart exerts a force of larger magnitude on the loaded cart.
(iii) neither cart exerts a force on the other.
(iv) the loaded cart and the empty cart, both exert an equal magnitude of force on each other.
(i) the loaded cart exerts a force of larger magnitude on the empty cart.
(ii) the empty cart exerts a force of larger magnitude on the loaded cart.
(iii) neither cart exerts a force on the other.
(iv) the loaded cart and the empty cart, both exert an equal magnitude of force on each other.

The correct option is (iv) both exert an equal magnitude of force on each other.
By Newton's third law, the two carts exert equal and opposite forces on each other, regardless of their masses.
Loaded cart
Empty cart
Heavier — more mass
Lighter — less mass
Force on the empty cart =
F
Force on the loaded cart =
F
Third law: the pair is
always equal
, whatever the load
Only the
accelerations
differ, because the masses differ
⇒ correct option is
(iv)
both exert an equal magnitude of force on each other
