The masses of your hand and your notebook are quite small, so the force of attraction between them is?

Question

a.) zero

b.) weak

Answer 1

weak, you can calculate the exact value by using the Gravitation Equation

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

where:

m1 = mass of hand
m2 = mass of notebook
G = universal gravitational constant = 6.67×10-11 m3 kg-1 s-2
d = distance between the two

If you want, you can use a d = 1 or 2 angstroms but never 0.
1 angstrom = 1.0 × 10-10 meters

As you can see, the only way the force would be zero is if one or the other object has a mass of zero.

Answer 2

It's b) weak.

Force between two objects are...

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

G = 6.6742 * 10^(-11) N * m^2 * kg^-2

I don't know how much your hand and your notebook weigh. If you know the weights of your notebook and your hand, try this out.

1) Multiply the weight of your hand and your notebook.

2) Multiply 0.000000000066742 to 1)

3) Divide it by 0.0001 (I assumed the distance between the center of mass of your hand and your notebook was 1 cm.)

That's about how much the force is between the notebook and your hand in Newton.

Answer 3

weak

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

G is a constant therefore as long as there is some mass there will be some force even if it is very little

Answer 4

("quite small") ≠ zero; ergo,
("quite small") = weak
