Answer:

resistance is also tripled

becomes 2/3R of actual resistance

Explanation:

R is directly proportional to length of the conductor.....so as length increases resistance also increases..so becomes three times

Radius=D/2

resistance is inversely proportional to radius..so D=2/resistance

3D=2/R

D=2/3R

I hope this helps you ☺️
