Two identically charged particles are fastened to the two ends of a spring of spring constant 100N/m and natural length 10cm. The system rests on a smooth horizontal table. If the charge on each particle is 2.0 x10-8 C,find the extension in the length of the spring.Asuume that the extension is small compared to the natural length.Justify this assumption after you have solved the problem.

A BEAUTIFUL LUV STORY:

He met her at a party, she was so outstanding, many guys chasing her,
while he was so normal,and nobody paid attention to him. At the end of
the party, he
invited her to have coffee with him, she was surprised, but as he was
polite, she agreed. They sat in a nice coffee shop, he was too nervous
to say anything, she felt uncomfortable, she thought, please, let me
back home.

Suddenly he asked the waiter : `would you please give me some salt ' ?
I'd like to put it in my coffee.

Everybody stared at him, so strange !
His face turned red, but, still, he put the salt in his coffee and
drank it.
She asked him curiously: why you have this hobby?
He replied: when I was a little boy, I was living near the sea, I liked
playing in the sea, I could feel the taste of the sea, salty and bite,
just like the taste of the salty coffee. Now every time I have the
salty coffee, I always think of my childhood, think of my hometown, I miss
my hometown so much, I miss my parents who are still living there.
While saying that, tears filled his eyes.
She was deeply touched. That's his true feeling, from the bottom of his
heart.
A man who can tell out he is homesick, he must be a man who loves home,
cares about home, has responsibility of home. Then she also started to
speak, spoke about her faraway hometown, her childhood, her family.
That was a really nice talk, also a beautiful beginning of their story.
They continued to date. She found actually he was a man who met all her
demands: he had tolerance, was kind hearted, warm, careful... he was
such a good person but she almost missed him ! Thanks to his salty coffee
!
Then the story was just like every beautiful love story: the princess
married to the prince, then they were living the happy life...
And, every time she made coffee for him, she put some salt in the
coffee, as she knew that's the way he liked it.
After 40 years, he passed away, left her a letter which said:
My dearest,
please forgive me, forgive for one whole life lie. This was the only
lie I said to you -- the salty coffee.
Remember the first time we dated ?
I was so nervous at that time, actually I wanted some sugar, but I said
salt. It was hard for me to change so I just went ahead. I never
thought that could be the
start of our communication! I tried to tell you the truth many times in
my life, but I was too afraid to do that, as I have promised not to lie
to you for
anything. Now I'm dying, I am afraid of nothing so I tell you the
truth: I don't like the salty coffee, what a strange bad taste...but I have
the salty coffee
for my whole life since I knew you, I never feel sorry for anything I
do for you. Having you with me is my biggest happiness for my whole
life. If I can live for the second time, I still want to know you and have
you for my whole life, even though I have to drink the salty coffee
again. Her tears made the letter totally wet.
Someday, someone asked her: what's the taste of salty coffee ?

It's sweet. She replied.

Try devoting yourself to someone who can drink salty coffee for you
whole life.................................
