A wire of mass M and length L lies on the x-axis with end A at the origin. Its linear mass density is , where x is measured from A. Mark the correct statement(s).

Options:(select one or more)
Answer:
A,B,C,D
Solution:
M=∫₀ᴸλ₀x dx gives λ₀=2M/L².
IA=∫₀ᴸx²λ₀x dx=ML²/2.
xcm=2L/3, so Icm=IA-Mxcm²=ML²/18.
IB=∫₀ᴸ(L-x)²λ₀x dx=ML²/6.
All four statements are correct.
