The weight of a body is 9.8 N at the place where g = 9.8 ms–2. Its mass is

zero

9.8 kg

10 kg

1 kg

- Weight is the force on an object due to gravity. It's calculated as weight (W) = mass (m) × acceleration due to gravity (g).

- In this case, the weight is given as 9.8 N. The gravitational acceleration (g) is 9.8 m/s².

- Rearranging the formula, mass (m) = weight (W) / acceleration due to gravity (g).

- Therefore, mass (m) = 9.8 N / 9.8 m/s² = 1 kg.

- Option:1 - zero: Mass can't be zero if the weight is non-zero.

- Option:2 - 9.8 kg: This implies a weight of 96.04 N at 9.8 m/s², incorrect for 9.8 N.

- Option:3 - 10 kg: This implies a weight of 98 N at 9.8 m/s², not matching 9.8 N.

- Option:4 - 1 kg: Correct. Matches calculated mass of 1 kg.
