Let e be the charge of the electron.
Then F1 + F2 = 0
F1 = K (-1.5) * (-e) /r1^2
F2 = K (15) * (-e) /r2^2
(-1.5) * /r1^2 + (15) /r2^2 = 0
-1 /r1^2 + (10) /r2^2 = 0
[r2/r1]^2 = 10
[R2/r1] = ± 3.162
r2 = ± 3.162 r1.
Given r1 + r2 = √ [1^2 + 0.5^2] = 1.1180-----1
Also tan θ = 0.5 => θ = 26.57°
====================================
Substituting r2 = 3.162 r1 in 1
4.162 r1=1.1180
r1 = 0.2686 m
x coordinate = r1 cos θ = 0.2403 m
y coordinate = r1 sin θ = 0.1201m
===================================
Substituting r2 = - 3.162 r1 in 1
-2.162 r1=1.1180
r1 = -0.5171m
x coordinate = r1 cos θ = -0.4625m
y coordinate = r1 sin θ = -0.2313m
===============================
In order to predict whether a star will eventually fuse oxygen into a heavier element, you mainly want to know about the star's mass.
<u>Explanation:</u>
Stellar evolution is procedure by which star experiences a succession of radical change during its lifetime. Depending upon the mass of stars, this lifetimes range from just two or three million years for most big to the trillions of years for a least massive, which is significantly longer or more than the age of universe.
All stars are conceived from falling billows of gas and residue, frequently called nebulae or sub-atomic mists. Throughout a large number of years, the protostar settles down into a condition of balance, turning out to be what is also known as the main- sequence - star.

<span>KE = 1/2mv^2 = (1/2)(2000)(2^2) = 4000 J This must equal the net work acting on the car. W=Fd The net force is 1140-950= 190N. so, d=W/F = 4000/190 = 21.05 m</span>
Ionic compound is the answer
