What is the weight of a 0.611 kg mass on Earth? (Use g ≈ 9.8 m/s^2)

What is the weight of a 0.611 kg mass on Earth? (Use g ≈ 9.8 m/s^2)

• A. 0.61 N
• B. 60 N
• C. 6 N
• D. 0.06 N

Answer: (C)

Weight is the gravitational force acting on a mass, F = m g. On Earth, g is about 9.8 m/s^2. So for a mass of 0.611 kg, the weight is 0.611 × 9.8 ≈ 5.99 N, which is about 6 newtons. The other numbers don’t fit because they would require gravity values quite different from Earth's (much smaller or much larger), whereas the correct weight for this mass under Earth gravity is around 6 N.
