Question

Given: Q1 = +20 µc = 2.0 x 10-5 C
Q2 = +30 µc = 3.0 x 10-5 C

K = 9.0 x 109 N·m2/C2
r = 3.0 m

Determine F.

_____ N



2.0 x 10-10

1.8

0.60

6.7 x 10-11

Answer 1

I have NOOOOO clue how to do this.

Answer 2

\[F=\frac{ k*Q _{1}*Q _{2} }{ R ^{2} } \]

You can use this..

Answer 3

The problem is I havent learned this before and i have very little info with no instruction on how to do it

Answer 4

I'm guessing B though?

Answer 5
