Ok im just here to check my answer for this question
a student places two 100 kg spheres a distance of 0.5 m apart. what is the gravitational force between the two spheres?
Fg= GmM/r^2
F= 6.67x10^-11(100)(100)/(0.5)^2
F= 2.67x10^-6 N
Correct me if I'm wrong
Looks good to me.
Thank you
Your calculation is incorrect. Let me explain the correct steps to find the gravitational force between the two spheres:
Step 1: Identify the given values:
- Mass of one sphere (m): 100 kg
- Mass of the other sphere (M): 100 kg
- Distance between the spheres (r): 0.5 m
- Gravitational constant (G): 6.67 × 10^-11 Nm^2/kg^2
Step 2: Apply the formula:
The formula to calculate the gravitational force between two objects is:
Fg = (G * m * M) / r^2
where:
- Fg is the gravitational force
- G is the gravitational constant
- m and M are the masses of the objects
- r is the distance between them
Step 3: Substitute the values into the formula:
Let's calculate the gravitational force:
Fg = (6.67 × 10^-11 Nm^2/kg^2) * (100 kg * 100 kg) / (0.5 m)^2
Fg = (6.67 × 10^-11 Nm^2/kg^2) * (10,000 kg^2) / 0.25 m^2
Step 4: Calculate the force:
Fg = (6.67 × 10^-11 Nm^2/kg^2) * 40,000 kg / 0.25 m^2
Fg = (6.67 × 10^-11 Nm^2/kg^2) * 160,000 kg/m^2
Fg = 1.0672 × 10^-5 N
So, the correct answer is approximately 1.0672 × 10^-5 Newtons (N).
Your initial calculation appears to have some mistakes, so the correct answer is different from what you calculated.
