Answer
- Correct option: (iv) the loaded cart and the empty cart both exert an equal magnitude of force on each other.
- Why: third-law forces are always equal in magnitude, whatever the masses are.
- (i) and (ii) are wrong because the load does not change the size of the force pair.
- (iii) is wrong because both carts definitely apply forces on each other during the collision.
