Answer:
36.22 mA
Explanation:
i1 = I , i2 = I, d = 8.2 cm = 0.082 m
Force per unit length = 3.2 nN/m = 3.2 x 10^-9 N/m
μo = 4 π × 10^-7 Tm/A
The formula for the force per unit length between the two wires is given by
F = μo / 4π x (2 i1 x i2) / d
3.2 x 10^-9 = 10^-7 x 2 x I^2 / 0.082
I = 0.0362 A = 36.22 mA
Answer:
The electric force on q₁ is
.
Explanation:
Given that,
Charge on ![q_{1}=-6.0\ \mu C](https://tex.z-dn.net/?f=q_%7B1%7D%3D-6.0%5C%20%5Cmu%20C)
Distance ![x= -3.0\ m](https://tex.z-dn.net/?f=x%3D%20-3.0%5C%20m)
Charge on
at origin
Distance ![x= 3.0\ m](https://tex.z-dn.net/?f=x%3D%203.0%5C%20m)
Charge on ![q_{3}=-1.0\ \mu C](https://tex.z-dn.net/?f=q_%7B3%7D%3D-1.0%5C%20%5Cmu%20C)
We need to calculate the electric force on q₁
Using formula of electric force
![F_{12}=\dfrac{kq_{1}q_{2}}{r^2}](https://tex.z-dn.net/?f=F_%7B12%7D%3D%5Cdfrac%7Bkq_%7B1%7Dq_%7B2%7D%7D%7Br%5E2%7D)
Put the value into the formula
![F_{12}=\dfrac{9\times10^{9}\times(-6.0\times10^{-6})\times1.0\times10^{-6}}{(3.0)^2}](https://tex.z-dn.net/?f=F_%7B12%7D%3D%5Cdfrac%7B9%5Ctimes10%5E%7B9%7D%5Ctimes%28-6.0%5Ctimes10%5E%7B-6%7D%29%5Ctimes1.0%5Ctimes10%5E%7B-6%7D%7D%7B%283.0%29%5E2%7D)
![F_{12}=-0.006\ N](https://tex.z-dn.net/?f=F_%7B12%7D%3D-0.006%5C%20N)
Negative sign shows the attraction force.
We need to calculate the electric force F₁₃
![F_{13}=\dfrac{9\times10^{9}\times(-6.0\times10^{-6})\times(-1.0\times10^{-6})}{(6.0)^2}](https://tex.z-dn.net/?f=F_%7B13%7D%3D%5Cdfrac%7B9%5Ctimes10%5E%7B9%7D%5Ctimes%28-6.0%5Ctimes10%5E%7B-6%7D%29%5Ctimes%28-1.0%5Ctimes10%5E%7B-6%7D%29%7D%7B%286.0%29%5E2%7D)
![F_{13}=0.0015\ N](https://tex.z-dn.net/?f=F_%7B13%7D%3D0.0015%5C%20N)
Positive sign shows the repulsive force.
We need to calculate the net electric force
![F=F_{12}+F_{13}](https://tex.z-dn.net/?f=F%3DF_%7B12%7D%2BF_%7B13%7D)
![F=-0.006+0.0015](https://tex.z-dn.net/?f=F%3D-0.006%2B0.0015)
![F=0.0045\ N](https://tex.z-dn.net/?f=F%3D0.0045%5C%20N)
![F=4.5\times10^{-3}\ N](https://tex.z-dn.net/?f=F%3D4.5%5Ctimes10%5E%7B-3%7D%5C%20N)
Hence, The electric force on q₁ is
.
Answer:
Things that have the same charge push each other away (they repel each other). This is called the Law of Charges. … Things that have more electrons than protons are negatively charged, while things with fewer electrons than protons are positively charged. Things with the same charge repel each other.
