How Do I Calculate Gravitational Force Between Two Objects?

Click For Summary
To calculate the gravitational force between two objects, the correct formula is Fg = (m1 * m2 / r^2) * G, where G is the gravitational constant (6.67e-11 N(m/kg)^2). In the example given, the masses are 46.0 kg and 52.0 kg, and the distance is 3.0 m. The correct calculation involves multiplying the masses together, not adding them, and then dividing by the square of the distance. The final answer should reflect this proper use of the formula to find the gravitational force accurately. Understanding the formula's components is crucial for solving such problems correctly.

Can anyone help me with this problem?

Approximate the gravitational force of attraction between a 46.0 kg girl and a 52.0 kg boy if they are sitting 3.0 m apart in physics class.

Since the formula is [(m1m2/r^2)]G=Fg. So I first tried [(46+52)/3^2]6.67e-11 and I got 7.27e-10. Then when the answer didn't work I thought maybe I was given the diamter, so i divided by 2, so I [(46+52)/1.5^2]6.67e-11, and I got 2.91e-8 and that was wrong to. I only have one more submission left to get this problem right, if you could help me it would be grately appreciated. Is there somthing special I need to do that I am missing? Thank-you

m1m2 = m1 * m2, not m1 + m2
 
yeah that's what i did wrong... thank-you

Thread 'Correct statement about size of wire to produce larger extension'
The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
