A negative charge of -2 C and a positive charge of 5 C are separated by 84,752 m. What is the force between the two charges?

F = 12.52 N

Explanation:

Given that,

Charge, q₁ = -2 C

Charge, q₂ = 5 C

The distance between charges, d = 84,752 m

We need to find the force between the two charges. The force between two charges is given by :

So, the force between charges is 12.52 N.

1)
table
x        f(x)
1        -7
2       -10
3       -13
4       -16

slope: rise / run = [-10-(-3)]/1 = -3
y-intercept: x=0=> y = -4 =b

equation: y = -3x - 4 this is the rule

2) table

x        f(x)
1         3
2         2
3         1
4         0

slope: rise / run = [2 -1] / [2 -  3] = -1
y-intercep: x = 0 => y = 4 = b

equation: y = -x + 4  this is the rule
