Answer:F/L = μ0*I²/2πd
Explanation:
Both wires carries current of the value (I) and are separated by the distance (d).
The length of both wires is (L).
The first wire creates a magnetic field of the magnitude according to Bio-savart law
B=(Uo * I)/2πd
This magnetic field has the ability to exert a force F on the second wire.
This force (F) is given as
F=BIL* sin θ
θ here is 90 because the magnetic field is perpendicular to the length of the second wire.
Thus the value of sin 90 = 1
Hence F= BIL
But B=(Uo * I)/2πd.
We have that F= B=[(Uo * I)/2πd] x IL
Thus we have that F= [Uo* I²/2πd] x L
By rearranging, and bringing L to the left hand side of the equation, we have that
F/L = [Uo* I²/2πd]
Answer:
true
Explanation:
with out trees we would have no air with out animals the envirounment would slowly decay
Hey!
Given ,
Acceleration, a = 5 m/s^2
time , t = 10 seconds
Initial velocity,u = 0
Final velocity , v = ?
We have ,
v = u + at
=> v = (0)+(5)(10)
=> v = 50 m/s
The electric potential energy of the charge is reduced because it decreases with increase in the distance between charges.
<h3>What is electric potential energy?</h3>
Electric potential energy can be defined as the energy needed to move a charge against an electric field.
It is calculated using the formula;
U = Kq1 q2 ÷ r
Where Q = electric potential energy
k = Coulombs constant
q1 and q2 = charges
r = distance of separation
Electric potential energy is inversely proportional to the distance of separation of the charges.
If the distance of the charges changes from 3mm to 6mm, then the electric potential energy of the charges is reduced because it decreases with increase in the distance of the charges.
Therefore, the electric potential energy of the charge is reduced because it decreases with increase in the distance between charges.
