Forces between 2 down quarks...could someone please help me : )
Hi
I am going slightly insane with this question I have!
"A neutron contains two down quarks at a separation of approximately 10^−15 m. Calculate the strength in Newtons of the electrical force between two down quarks at a separation of 1.0 × 10^-15 m."
Now I have used F= k x (Q1 x Q2 / r (squared))
so...
F = 9 x 10^9 x ((1/3) x (-1.6 x 10^-19 C))(squared) / (1.0 x 10^-15 m )(squared)
and I get 25.6 N
Im pretty sure this is wrong, I am sure its much higher than that.
Could anybody tell me where I am going wrong please.
Thanks
Danny
