A sphere weighs 0.98 N on the Earth. It is brought on the Moon and is divided into 10 equal parts there. Which one among the following is the mass of each part on the Moon in SI unit? (The acceleration due to gravity on the surface of the Moon is one-sixth that of on the Earth)

To find the mass, we use the formula W = m × g. On Earth, the weight (W) is 0.98 N and the acceleration due to gravity (g) is approximately 9.8 m/s2. Thus, the mass (m) of the sphere is 0.98 / 9.8 = 0.1 kg.

Mass is an intrinsic property of matter and does not change with location; therefore, the mass of the sphere remains 0.1 kg on the Moon. When the sphere is divided into 10 equal parts, the mass of each part is calculated as 0.1 kg / 10 = 0.01 kg. Although the acceleration due to gravity on the Moon is one-sixth that of Earth, this only affects the weight of the object, not its mass. In SI units, the mass of each part is 0.01 kg.
