Question

. 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) ρ2
(c) 2 ρ
(d) 4 ρ

Answer 1

Answer:

the answer is 4p

resistivity varies with square

Answer 2

Answer:

Ans- a Roh (p)

Explanation:

Resistivity is the property of material and not depends on the area and length of the wire
