Answer:
The result of 1 + 0.5 + 1 + 2 - 4.5 is 0.
Gravitation is the force of attraction between two masses. It is the force that causes objects to fall to the ground and keeps planets in orbit around the sun.
The value of acceleration due to gravity 'g' at the polar region is approximately 9.8 m/s^2.
The weight of a body is directly proportional to its mass. Hence, to calculate the mass of a body with a weight of 600 N on the surface of the Earth, you can use the formula: mass = weight / g, where g is the acceleration due to gravity (approximately 9.8 m/s^2 at the Earth's surface). The mass of the body would be approximately 61.2 kg.
