What is the equation for calculating the electrical force, Fe, between two charges? Fe = kStartfraction q Subscript 1 baseline times q Subscript 2 baseline over d Endfraction. Fe = Startfraction q Subscript 1 baseline times q Subscript 2 baseline over d Superscript 2 baseline Endfraction. Fe = kStartfraction q Subscript 1 baseline times q Subscript 2 baseline over d Superscript 2 baseline Endfraction. Fe = kStartfraction q Subscript 1 baseline times q Subscript 2 baseline over d Endfraction Superscript 2 baseline.

Step-by-step explanation:

According to coulombs law "the force of attraction or repulsion between two charges Q1 and Q2 in a given medium is directly proportional to the product of their charges and inversely proportional to the square of the distance separating them"

where

k = constant of proportionality ()

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
