If you were to place an object with the mass of the Sun on the surface of the Earth, its weight would be determined by the force of gravity between the object and the Earth. The weight of an object can be calculated using the formula:
Weight = Mass × Acceleration due to Gravity
The mass of the Sun is approximately 1.989 × 10^30 kilograms, and the acceleration due to gravity on the surface of the Earth is approximately 9.8 meters per second squared.
Weight = (1.989 × 10^30 kg) × (9.8 m/s^2)
Calculating this, we find that the weight of an object with the mass of the Sun on the surface of the Earth would be approximately 1.951 × 10^31 newtons.
