The electric potential at the centre of two concentric half rings of radii R₁ and R₂ , having same linear charge density ' ' is ( ₀= permittivity of free space )
Options
- A2 ₀
- B2 ₀
- C4 ₀
- D₀
Correct answer
B. 2 ₀
Step-by-step solution
aligned & V ₁= 1 4 ₀ ( R ₁ ) R ₁ & ~V ₂= 1 4 ₀ ( R ₂ ) R ₂ & ~V _ net = V ₁+ V ₂= 1 4 ₀ 2= 2 ₀ aligned
