Planet Mars has a mass of 6.4 × 1023 kg, and you have a mass of 5.0 × 101 kg. What force of gravity is exerted between you and Mars, if you are standing on its surface?

gotta know the radius of Mars, since

F = GmM/r^2

everything else you have.

The question was missing the radius of Mars which is 3.43 x 10^6 m.

Fg=GMm / r^2
=(6.67 x 10^-11)(6.47 x 10^23)(50) / (3.43 x 10^6)^2
Fg=1.8 x10^2 N

To calculate the force of gravity between you and Mars, we can use Newton's Law of Universal Gravitation. The formula is:

F = (G * m1 * m2) / r^2

Where:
F is the force of gravity,
G is the gravitational constant (6.67430 × 10^-11 N m^2/kg^2),
m1 is the mass of the first object (your mass),
m2 is the mass of the second object (Mars' mass),
r is the distance between the centers of the two objects (in this case, the radius of Mars).

In this case:
m1 (your mass) = 5.0 × 10^1 kg
m2 (Mars' mass) = 6.4 × 10^23 kg
The radius of Mars is not given, but we can assume it as the average distance from Mars' surface to its center, which is approximately 3.4 × 10^6 meters.

So, plugging in the values:

F = (6.67430 × 10^-11 N m^2/kg^2 * 5.0 × 10^1 kg * 6.4 × 10^23 kg) / (3.4 × 10^6 meters)^2

Calculating this equation will give us the force of gravity exerted between you and Mars.

To calculate the force of gravity between you and Mars, we can use the formula for Newton's law of gravitation:

F = (G * m1 * m2) / r^2

Where:
F is the force of gravity
G is the gravitational constant (approximately 6.67430 × 10^-11 N * (m/kg)^2)
m1 and m2 are the masses of the two objects
r is the distance between the centers of the two objects

In this case, let's assume that you are standing on the surface of Mars, so the distance (r) between you and the center of Mars would be the radius of Mars, which is approximately 3390000 meters.

Plugging in the values:
m1 (your mass) = 5.0 × 10^1 kg
m2 (Mars' mass) = 6.4 × 10^23 kg
r (distance) = 3390000 meters

F = (6.67430 × 10^-11 N * (m/kg)^2) * (5.0 × 10^1 kg) * (6.4 × 10^23 kg) / (3390000 meters)^2

Now let's calculate the force using these values:
F = (6.67430 × 10^-11) * (5.0 × 10^1) * (6.4 × 10^23) / (3390000)^2

The force of gravity between you and Mars, when you are standing on its surface, would be the answer to this equation.
