One day a human being will land on mars. mars has a diameter of 6786 km and a massof 6.42 × 1023 kg. if you weighed 834 n on earth, how much would you weigh on mars?

If you weighed 834N on earth, you will weigh 31.6N on Mars.

On earth the acceleration due to gravity is 9.81 m/s². Since the weight on earth is 834N, hence:

Weight = mass * acceleration due to gravity

834 = mass * 9.81

Mass = 85 kg

The acceleration due to gravity (g) on Mars is:

g = GM/r²

Where G = gravitational constant = 6.67 * 10⁻¹¹ Nm²/kg², r is radius, M = mass

M = 6.42 × 10²³ kg, r = diameter / 2 = 6786 km / 2 = 3393 km = 3393000 m. Hence:

g = 6.67 * 10⁻¹¹ * 6.42 × 10²³ / (3393000)² = 3.72 m/s³

Weight on Mars = 85 kg * 3.72 m/s² = 31.6 N
