The magnetic field strength is 17 Weber.
<h3>How can we find the value of magnetic field?</h3>We know, The magnetic field equation is given by:
Where, we know,
=
= It is the magnetic constant or the permeability of free space.
n = The turn density which is equivalent to number of turns per unit length = 3300 turns per meter = 3300
I= the amount of current applied to it = 4. 1 kA = 4 × A.
We have to find the magnetic field strength = B
Substituting the known values into the equation gives the strength of the magnetic field, which is:
[We know,
]
So, from the above calculation we can see that, The magnetic field strength is 17 Weber.

Answer:
F = 0.1575 N
Explanation:
When the third sphere touches the first sphere, the charge is distributed between both spheres, then now the first sphere has only half of his original charge.
In this moment then
Sphere one has a charge = Q/2
Sphere three has a charge = Q/2
Now when the third sphere touches the second sphere again the charge is distributed in a manner that both sphere has the same charge.
How the total charge is Q = Q/2 + Q = 3/2Q, when the spheres are separated each one has 3/4Q
Sphere two has a charge = 3/4Q
Sphere three has a charge = 3/4Q
The electrostatic force that acts on sphere 2 due to sphere 1 is:
F =
F=
how = 0.42
Then
F =
F = 0.1575 N
