Density is (the object's mass) divided by (the object's volume).
Changing the object's shape doesn't change its mass or volume,
so its density doesn't change.
The force will be doubled if direction of one current is reversed and doubled.
The force between two parallel currents I₁ and I₂ that are spaced apart by r is measured as the ratio F/L. If the currents are flowing in the same direction, the force is attracting; if not, it is repulsive.
With a distance of 4.00 cm between them, two parallel wires repel one another with a force of 2.00 × 10⁻⁴ N/m. One wire is carrying 5.00 A of current.
I₁ = 5 A
d = 4 cm
F = 2 × 10⁻⁴ N/m
We have, F/L = μ₀ I₁ I₂ / L
Now, we know the force is directly proportional to the product of the current, and the direction of one current is reversed and doubled.
The force of interaction would become attractive and its magnitude would double as a result of switching the directions of either of the currents and doubling their size.

B. located in the atom's nucleus.
Explanation:
Rutherford's experiment using a beam of alpha particles aimed at a sheet of gold foil led him to conclude that an atom's mass is located in the atom's nucleus.
- In his experiment, he bombarded a thin gold foil with alpha particles.
- He found that most of the alpha particles passed through the foil while a few of them were deflected back.
To explain this, he suggested an atomic model(nuclear model) in which an atom is made up of a small positively charged center or nucleus.
The mass is concentrated in the nucleus.
A large space containing electrons further surrounds the nucleus.
