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
Distance
Charge on at origin
Distance
Charge on
We need to calculate the electric force on q₁
Using formula of electric force
Put the value into the formula
Negative sign shows the attraction force.
We need to calculate the electric force F₁₃
Positive sign shows the repulsive force.
We need to calculate the net electric force
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.
