The proton (positive charge) shall be closer to the charge with the lower magnitude  which is at the orgin.

The proton also shall be out of the interval between the two charges so that the pull of one charge cancels with the push of the other.

The region at which those conditions happen is to the left of the origin.

In that case the forces over the proton shall be:

k* (2.4 nC) * p / (x^2) - k*(4.8 nC) * p /( 1.3 + x)^2 = 0


where p is the charge of the proton.

You can simplify k and p:

2.4 / x^2 - 4.8 / (1.3 + x)^2 = 0

You can also simplify by 2.4

1/ x^2 - 2 / (1.3 + x)^2 = 0

(1.3+x)^2 - 2x^2 = 0

1.69 + 2.6x + x^2 - 2x^2 = 0

1.69 + 2.6x - x^2 = 0

x^2 -2.6x - 1.69 =0

Solve using the quadratic formula: x = 3.14 (use only the positive value)

That is the proton shall be place 3.14 units to the left of the origin (positive charge)

What is a catchy slogan to help people remember the difference between weathering and erosin
GaryK [48]
These are more of ideas to help your brain invent something less chessy...
Erosion is like corrosion, with no acid.
Erosion happens 'cuz the surface get frozen and beaten by the ocean. (they kinda rhyme) :)
Erosion is the transportation of, the deportation... 
~OR~
I cant think of anything for weathering but i got something good, but its still cheesy/ ):

Erosions' got the grooves and so it moves. But weathering breakdown and changes so its molecules changes.
I'm sorry these kinda suck...

Two 10-cm-diameter charged rings face each other, 21.0 cm apart. Both rings are charged to +40.0 nC. What is the electric field
Katyanochek1 [597]

Complete question:

Two 10-cm-diameter charged rings face each other, 21.0 cm apart. Both rings are charged to +40.0 nC. What is the electric field strength  at the midpoint between the two rings ?

Answer:

The electric field strength at the mid-point between the two rings is zero.

Explanation:

Given;

diameter of each ring, d = 10 cm = 0.1 m

distance between the rings, r = 21.0 cm = 0.21 m

charge of each ring, q = 40 nC = 40 x 10⁻⁹ C

let the midpoint between the two rings = x

The electric field strength  at the midpoint between the two rings is given as;

E_{mid} = E_{right} +E_{left}\\\\E_{right}  = \frac{KQ}{(x^2 + r^2)^\frac{2}{3} } \\\\E_{leftt}  = -\ \frac{KQ}{(x^2 + r^2)^\frac{2}{3} }\\\\E_{mid} = \frac{KQ}{(x^2 + r^2)^\frac{2}{3} }  - \frac{KQ}{(x^2 + r^2)^\frac{2}{3} } = 0

Therefore, the electric field strength at the mid-point between the two rings is zero.
