Final answer:

The weight of an object on the Moon can be calculated by multiplying its mass by the gravity on the Moon, which is 1.67 m/s². A mass of 48g (0.048kg) would thus have a weight of approximately 0.08 N on the Moon, which is not listed among the given options.

Step-by-step explanation:

The weight of a body on the Moon can be calculated by understanding that the Moon's gravity is about 1/6th of Earth's gravity. If an object weighs 9.8 N on Earth (due to the gravity of 9.8 m/s²), it would weigh approximately 1.63 N on the Moon.

Given a body with a mass of 48g, which is equivalent to 0.048kg (since 1000g = 1kg), we can calculate the weight on the Moon by using the formula:

Weight (W) = mass (m) × gravity (g)

Weight on the Moon = 0.048 kg × 1.67 m/s² (gravity on the Moon)

Hence the weight of the body on the Moon would be 0.08 N when rounded to two significant figures.

Therefore, none of the provided options (a. 8 N, b. 6 N, c. 2 N, d. 4 N) are correct. If we have to choose the closest value, it would be 'c' which is 2 N, but it is still not the correct weight.
