Mass remains constant; weight varies with gravitational field strength Steps:

• Calculate the object's mass using Earth's data: mass = weight / g = 10 N / 10 N/kg = 1 kg.
• Mass does not change when moving to another planet.
• Calculate the weight on the new planet: weight = mass × g_planet = 1 kg × 4 N/kg = 4 N.
• The correct row is therefore 1.0 kg and 4.0 N.

Why B is correct:

• Not correct; it uses wrong mass (4 kg instead of 1 kg) and wrong weight (16 N instead of 4 N).

Why the others are wrong:

• A: Swaps and miscalculates values (mass 4 kg too high, weight 1 N too low).
• C: Mass 40 kg way too high; weight 16 N too high.
• D: Mass 400 kg and weight 1600 N both absurdly inflated.

Not enough information to match any option exactly, but physics shows none fit. Final answer: None of the options are correct
