A body of mass 20kg is transferred from earth (grams=weight newton kg) to another planet where G=2 Newton kg,
1.Wat is the mass on earth?
2.wat is the wieght on earth?
3.wat is the mass on the other planet?
4.wat is the weight on the other planet?
To find the answers to these questions, we need to understand some basic concepts.
1. Mass on Earth: The mass of a body is constant regardless of the gravitational force. So, the mass on Earth will still be 20 kg.
2. Weight on Earth: Weight is the force experienced by a body due to gravity. It is calculated using the formula W = m * g, where W is weight, m is mass, and g is the acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.8 m/s^2. Therefore, the weight on Earth will be W = 20 kg * 9.8 m/s^2 = 196 N.
3. Mass on the Other Planet: The mass of a body does not change when it is transferred to another planet. So, the mass on the other planet will still be 20 kg.
4. Weight on the Other Planet: The weight on the other planet can be calculated using the formula W = m * g, where W is weight, m is mass, and g is the acceleration due to gravity on the other planet. In this case, g is given as 2 N/kg. Therefore, the weight on the other planet will be W = 20 kg * 2 N/kg = 40 N.
