Calculate the weight of a 60 kg person on Earth (g = 9.8 N/kg).

Answer and explanation

Correct answer: A. 588 N

  1. Step 1: Weight = mass × gravitational field strength.
  2. Step 2: 60 × 9.8 = 588 N.
Answer
588 N.
Why not the others: 6.1 N: the mass was divided by g. 60 N: the mass was used as the weight. 58.8 N: the decimal point was misplaced.
