Answer:
The closer together the field lines are, the stronger the field. As you can see the field is very strong in the center of the magnet, but because they are mostly contained in the magnet itself, the field is very weak in the air near the center.

Answer:
When studying atoms, scientists can ignore the <em><u>intermolecular</u></em><em><u> </u></em><em><u>electrostat</u></em><em><u>ic</u></em><em><u> </u></em>forces between charged particles that make up the atoms because it is many millions of times smaller than other forces in the atom. Gravitational Constant Normal Fricitional
Q = magnitude of charge on each of the two point charge = 3.60 mC = 3.60 x 10⁻³ C
r = distance between the two point charges = 9.3 cm = 0.093 m
k = constant = 9 x 10⁹ Nm²/C²
F = magnitude of the force between the two point charges = ?
according to coulomb's law , force between two charges is given as
F = k Q²/r²
inserting the values
F = (9 x 10⁹) (3.60 x 10⁻³)²/(0.093)²
F = 1.35 x 10⁷ N
