Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially atx1 = 14.7 mm.In this confi
Sladkaya [172]

Answer:

The force magnitude is 1.75 μN acting outward from the origin towards x₂

Explanation:

The given parameters, are;

The location of q₁ = The origin

The location of q₂ = 14.7 mm from q₁

The repulsive force exerted on q₂ by q₁ = 2.62 μN

The location the particle q₂ is located to =  18.0 mm from q₁

By Coulomb's law, we have;

F = k\dfrac{q_1 \times q_2 }{r^2}

Where;

k = Coulomb constant ≈ 8.99 × 10⁹ kg·m³/(s²·C²)

r = The distance between the particles

F = The force acting between the particles

When r = 14.7 mm F = 2.62 μN

∴ q₂ × q₁ = r² × F/k = (14.7×10^(-3))²×2.62×10^(-6)/(8.9875517923^9) ≈ 1.48 × 10⁻¹⁸

q₂ × q₁ = 1.48 × 10⁻¹⁸ C²

When the distance is increased to 18.0 mm, we have;

F = (8.9875517923^9) × 1.4796647 × 10^(-18)/((18×10^(-3))²) = 1.75 × 10⁻⁶ N

∴ F = 1.75 μN.

Therefore;

The force magnitude is 1.75 μN outward from the origin towards  x₂.

What is the energy difference between parallel and antiparallel alignment of the z component of an electron's spin magnetic dipo
Readme [11.4K]

Answer:

\Delta U= 4.8204\times10^{-24} J

Explanation:

The difference between parallel and anti parallel alignment of the z component of an electron's spin magnetic dipole moment  is given by

U_1-U_2= (-\mu Bcos(\theta_2))-(-\mu Bcos(\theta_1))

where  μ= dipole moment B= strength of magnetic field and θ= angle between direction of magnetic field and dipole

here θ_2 and θ_1 are 180 and 0° respectively.

U_1-U_2= (\mu B)-(-\mu B)

U_1-U_2= 2\mu B

here μ is bohr magnetron or  magnetic moment of an electron = 9.27×10^{-24}

put this value we get

U_1-U_2= 2\times 9.27\times10^{-24}(0.26)

\Delta U= 4.8204\times10^{-24} J
