A 10 kg object has a weight of approximately ___ on Earth (taking g = 10 m/s²):
A1000 N
B10 N
C1 N
D100 N
Answer & Solution
Correct answer: D. 100 N
Weight = mass × g = 10 × 10 = 100 N on Earth. So a 10 kg mass weighs about 100 newtons under Earth's gravity. (On the Moon, with g ≈ 1.6 m/s², the same mass would weigh only ~16 N.)
