astra-53 [7]

Answer: It will remain the same

Explanation:

According to Coulomb's Law:

"The electrostatic force $F_{E}$ between two point charges $q_{1}$ and $q_{2}$ is proportional to the product of the charges and inversely proportional to the square of the distance $d$ that separates them, and has the direction of the line that joins them".

Mathematically this law is written as:

$F_{E}=K\frac{q_{1}.q_{2}}{d^{2}}$ (1)

Where:

$F_{E}$ is the electrostatic force

$K$ is the Coulomb's constant

$q_{1}=q_{2}=q$ are the electric charges , which in this case have the same positive charge

$d$ is the separation distance between the charges

Rewritting we have:

$F_{E}=K\frac{q^{2}}{d^{2}}$ (2)

Now, if the first charge is doubled:

$q_{1}=2q_$

And the second is reduced to a half:

$q_{2}=\frac{1}{2}q$

We will have the following:

$F_{E}=K\frac{(2q)(\frac{1}{2}q)}{d^{2}}$ (3)

$F_{E}=K\frac{q^{2}}{d^{2}}$ (4)

As we can see equation (4) is equal to equation (2), this means the force of repulsion between both charges will remain the same

postnew [5]

The correct answer of the given question above would be option B. The statement that is not correct is that, a steady magnetic field produces a steady current. The rest of the statements are all correct. An unchanging/static magnetic field (relative to a wire/circuit) induces zero current.
