The subatomic particles that acts like a mini-magnet is electron. Electrons are negatively charged sub atomic particles in an atom. The electron spin is a property of an electron that makes it behave like it's spinning; a spinning electron produces a magnetic field that makes it behave like a tiny magnet in an atom.
Answer:
A
Explanation:
You did not list the options. However, knowing the possible options from having seen the material myself - I can infer that the answer option is A. I apologize sincerely if this is wrong.
Answer:
= 0.0298V
Explanation:
Electric field between two conductor = σ / ε₀
σ = 33pC/m²
= 33 × 10⁻¹²C/m²
ε₀ = 8.85 × 10 ⁻¹²C²/Nm²
E = 33 × 10⁻¹² / 8.85 × 10 ⁻¹²
= 3.7288N/C
potential difference between two conductors = Ed
where d = 8mm = 8 × 10 ⁻³m
V = 3.7288 × 8 × 10 ⁻³
= 29.83 × 10 ⁻³
= 0.0298V
