A wire of length l, made of material resistivity ρ is cut into two equal parts. The resistivity of the two parts are equal to, (a) ρ    (b) 𝜌 /2      (c) 2 ρ     (d) 4 ρ 

Dear Student,
Resistivity of a material is a material property and depends on the type of material and not on its dimensions. Hence, the resistivity of the two parts will be equal to ρ.
Ans (a)
