What is the electrical force between q1 and q2? Recall that k = 8.99 * 109 N•meters squared over Coulombs squared ... 4.3 * 10 N 3.5 * 10 N - 5.4 * 10 N - 5.8 * 10 N?

c - 5.4 * 1010 N on edge

Incomplete question but for understanding.

We want to find the electrical force between two charges, then you can use the coulombs law which states that the force of attraction or repulsion between two charges is directly proportional to the product of the two charges and inversely proportional to the square of their distance apart,

So,

F = kq1•q2 / r²

Where k is a constant and it is given as

K = 8.99 * 10^9 Nm²/C²

q1 and q2 are the charges and in this question it is not given, so the question is incomplete. Let assume that,

q1 = - 1.609 * 10^-19 C electron

q2 = 1.609 * 10^-19 C proton

Since unlike charges attract, then it is force of attraction

Also, r is the distance apart and it is not given, let assume the distance between the two charges is 2 * 10^-5m

Then,

F = kq1•q2 / r²

F = 8.99 * 10^9 * 1.609 * 10^-19 * 1.609 * 10^-19 / (2 * 10^-5) ²

F = 5.82 * 10^-19 N
