Solution
In this question we have given
Charge,![q_{1}=-5\times 10^-9C](https://tex.z-dn.net/?f=q_%7B1%7D%3D-5%5Ctimes%2010%5E-9C)
Charge,![q_{2}=-1.5\times 10^-9C](https://tex.z-dn.net/?f=q_%7B2%7D%3D-1.5%5Ctimes%2010%5E-9C)
Charge,![q_{3} =1.1\times 10^-8C](https://tex.z-dn.net/?f=q_%7B3%7D%20%3D1.1%5Ctimes%2010%5E-8C)
Distance between Charge
and
,d=43cm=.43m
Let the distance between charge
and
, is x
Therefore,distance between charge
and
, will be=(.43-x)
We know By Couloms law, Force on Charge
due to charge
which are seperated by distance d is given by following equation
............(1)
Here, K=![9\times 10^9 Nm^2C^-2](https://tex.z-dn.net/?f=9%5Ctimes%2010%5E9%20Nm%5E2C%5E-2)
Therefore,
Force on Charge
due to charge ![q_{1}](https://tex.z-dn.net/?f=q_%7B1%7D)
..(2)
Similarly,
Force on Charge
due to charge ![q_{2}](https://tex.z-dn.net/?f=q_%7B2%7D)
..(2)
In equilibrium condition,
![F_{1} =F_{2}](https://tex.z-dn.net/?f=F_%7B1%7D%20%3DF_%7B2%7D)
![-\frac{k\times 5\times 10^-9C\times 1.1\times 10^-8C}{x^2}=-\frac{k\times 1.5\times 10^-9C\times 1.1\times 10^-8C}{(.43-x)^2}](https://tex.z-dn.net/?f=-%5Cfrac%7Bk%5Ctimes%205%5Ctimes%2010%5E-9C%5Ctimes%201.1%5Ctimes%2010%5E-8C%7D%7Bx%5E2%7D%3D-%5Cfrac%7Bk%5Ctimes%201.5%5Ctimes%2010%5E-9C%5Ctimes%201.1%5Ctimes%2010%5E-8C%7D%7B%28.43-x%29%5E2%7D)
![\frac{5\times 10^-9C}{x^2}=\frac{1.5\times 10^-9C}{(.43-x)^2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Ctimes%2010%5E-9C%7D%7Bx%5E2%7D%3D%5Cfrac%7B1.5%5Ctimes%2010%5E-9C%7D%7B%28.43-x%29%5E2%7D)
![5\times 10^-9C \times (.43-x)^2=1.5\times 10^-9C\times (x)^2](https://tex.z-dn.net/?f=5%5Ctimes%2010%5E-9C%20%5Ctimes%20%28.43-x%29%5E2%3D1.5%5Ctimes%2010%5E-9C%5Ctimes%20%28x%29%5E2)
![3.5x^2-4.3x+.9245=0](https://tex.z-dn.net/?f=3.5x%5E2-4.3x%2B.9245%3D0)
on solving we get
x=.277m
0r x=28cm
The distance between charge
and
, is 28cm
The answer is D.

Answer:
A step by step to walk
Explanation:
One- Make sure your shoes are tied so that you dont trip
Two- Make sure your way is a cleared path so you dont fall or even hurt yourself
three- use both set of lets to go in any direction you want.
Four- when walking make sure to try and keep a steedy pace so that both set of legs are going up and down but in harmony
