calculate the force of gravity on a 1.2 x 10^5 kg space station at a distance of 3.5 x 10^5 m from earth's surface

earth equal to 5.98 x 10^24 kg

To calculate the force of gravity on an object, we can use the formula:

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 is the mass of the first object (in this case, Earth)
m2 is the mass of the second object (in this case, the space station)
r is the distance between the centers of the two objects

Let's plug in the values given in the question:

m1 = 5.98 x 10^24 kg
m2 = 1.2 x 10^5 kg
r = 3.5 x 10^5 m

Calculating:

F = (6.67430 × 10^-11 N(m/kg)^2) * (5.98 x 10^24 kg) * (1.2 x 10^5 kg) / (3.5 x 10^5 m)^2

To simplify the calculation, let's multiply the values in the numerator first:

F = (8.00916 × 10^9 N(m/kg)^2) / (3.5 x 10^5 m)^2

Next, let's square the value in the denominator:

F = (8.00916 × 10^9 N(m/kg)^2) / (1.225 × 10^11 m^2)

Finally, divide the numerator by the denominator:

F = 6.54 N

Therefore, the force of gravity on the 1.2 x 10^5 kg space station at a distance of 3.5 x 10^5 m from Earth's surface is approximately 6.54 N.
