JEE MainPhysicsCurrent ElectricityMCQ+4 / −1
A metal wire of resistance 3 Ω\OmegaΩ is elongated to make a uniform wire of double its previous length. This new wire is now bent and the ends joined to make a circle. If two points on this circle make an angle 60° at the centre, the equivalent resistance between these two points will be :-
  1. A
    5 /2 Ω\OmegaΩ
  2. B
    12/5 Ω\OmegaΩ
  3. C
    7/2 Ω\OmegaΩ
  4. D
    5 / 3 Ω\OmegaΩ
