Describe every variable/letter in Coulomb's Law with units.
F = (kq_1q_2)/r^2
k = constant (9.0 x 109 Nm2/C2)
q1 = first charge (C)
q2 = second charge (C)
r = distance between charges (m)

Consider the electric field lines shown in the diagram below. Would the charges attract, repel or neither? AND what are their charges?
Attract.
A is positive, B is negative.

What gravitational force does the moon produce on the Earth if their centers are 3.88 x 108 m apart and the moon has a mass of 7.34 × 1022 kg and the Earth has a mass of 5.97 × 1024 kg?
FG = 1.9 x 1020 N

Imagine a negatively charged electron placed on Point A. Which way will the electron move? AND Where would an electron feel a stronger force between Point A and Point B?
**insert image**
Towards because opposite charges attract.
Point B because point B is closer to the proton (+).

How far apart would two electrons be in order to have the same amount of force between them as the moon and Earth as the previous problem?
k = 9 × 109 Nm2/C2
qelectron = -1.6 x 10-19 C
FG = 1.94x 1020 N
r = sqrt((k times q_1 times q_2)/F_G
r = 1.09 x 10-24 m

What is the mass of Earth given:
G = 6.67 x 10-11 Nm2 / kg2,
F = 3.5 x 1022 N,
mSun = 2.0 x 1030 kg,
rSun and Earth = 1.5 x 1011 m
m_(earth) = (F times r_(Sun and Earth)^2)/(G times m_(Sun
mEarth = 5.9 x 1024 kg
This is Earth's mass!
