Peter
Because you'll just hack into his phone!
Ned
*sad sigh*
Peter
Smh
Ned
Pleeeeeease
Peter
No.

>>>You are now texting Dr. Ruffalo and Coffee Einstein<<<
Parker
Hello!!
Dr. Ruffalo
Good afternoon Mr. Parker
Coffee Einstein
Sup kid
Dr. Ruffalo
Aren't you in a meeting?
Coffee Einstein
Not an important one
Dr. Ruffalo
Kind of important
Parker
A business meeting?
Coffee Einstein
More like a... non-business meeting
Parker
CoOl
Coffee Einstein
(;
Parker
:D
Dr. Ruffalo
Back on topic please
Parker
Sorry
Dr. Ruffalo
I believe I said we're starting Electrostatic Problems today, correct?
Parker
Yup!
Dr. Ruffalo
Alright. I'll walk you through the first one, then see if you can answer the rest on your own
Sound good?
Parker
Yup
Dr. Ruffalo
Great
Two identical objects, separated by a distance d, with charges equal in magnitude but of opposite signs exert a force of attraction of - 2.5 N on each other. What force do these objects exert on each other if the distance between them becomes 2d?
Let the two charges be q and -q. The magnitude of the force that q and -q, separated by a distance d, exert on each other is given by which law?
Parker
Coulomb's law
Dr. Ruffalo
Which is?
Parker
F = k (q) (- q) / d2 = - k q2 / d2 = - 2.5 N
Dr. Ruffalo
Correct.
So the magnitude of the force F2 that q and -q, separated by a distance 2 d, exert on each other is given by Coulomb's law, which would equal
Coffee Einstein
F2 = k (q) (- q) / (2 d)2 = - k q2 / 4 d2 = F / 4 = - 2.5 / 4 = - 0.625 N
