A solid sphere is rotating about an axis as shown in figure. An insect follows the dotted path on the circumference of sphere as shown. Then, match the following columns ( array |c|l|c|l| & Column I & & Column II (A) & Moment of inertia & (p) & Will remain constant (B) & Angular velocity & (q) & Will first increase, & & & then decrease (C) & Angular momentum & (r) & Will first decrease, & & & then increase (D) & Rota

Options

  1. Aa-q b-r c-p d-r
  2. Ba-p b-s c-r d-q
  3. Ca-q b-r c-s d-p
  4. Da-q b-p c-s d-r

Correct answer

A. a-q b-r c-p d-r

Step-by-step solution

( aligned & t=0 & L= constant , K= L^2 2 I and I = constant , aligned ) Insect first moves away from the axis, the towards it. Hence, I will first increase and then decrease.
