  • a)
    5.77 × 105 W
  • b)
    5.77 × 10-5 W
  • c)
    5.77 × 10-7 W
  • d)
    5.77 × 107 W
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
A hollow copper tube of 5 m length has got external diameter equal to ...
Cross sectional area of the copper tube is:
A=(π/4)​(d12​−d22​)=(π/4)​(102−92)=14.9cm2=14.9∗10−4m2
l=5m
ρ=1.7∗10−8
Resistance is given by: R=ρl/A​=5.77 x 10−5Ohm

R=pl/A,where p is specific resistance
R=pl/2πrt. t-thickness
R=(1.7×10^-8×5)/2π(5×10^-2)(5×10^-3)
R=5.77×10-5 ohm
