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?
havent I responded to this?
To answer these questions, we need to understand the concepts of mass and weight, as well as how they relate to the force of gravity.
1. The mass of the body remains the same regardless of the planet it is on. So, the mass on Earth will still be 20 kg.
2. Weight is the force exerted on an object due to gravity. Weight can be calculated using the formula: Weight = mass × gravity. On Earth, the value of gravity is approximately 9.8 m/s^2. Plugging in the values, we get:
Weight on Earth = 20 kg × 9.8 m/s^2 = 196 N (Newton).
3. To determine the mass on the other planet, we can equate the weight on Earth to the weight on the other planet, using the formula mentioned earlier. Rearranging the formula, we get:
Mass on other planet = Weight on Earth / gravity of the other planet.
Since the gravity of the other planet is given as G=2 N/kg, plugging in the values, we get:
Mass on other planet = 196 N / 2 N/kg = 98 kg.
4. To find the weight on the other planet, we can use the same formula as before:
Weight on other planet = mass on other planet × gravity of the other planet.
Plugging in the values, we get:
Weight on other planet = 98 kg × 2 N/kg = 196 N.
