Answer 1

Answer:

The value of q1 and q2 in electrostatics signifies that

Explanation

The given question is solved using the resistivity factor involved to calculate the resistance of the given wire with length and diameter.

Given is the length and diameter of the copper wire as length l = 1.0 km = 1000 m

Diameter d = 0.50 mm

Diameter d=2 \times× radius
