Physics · Classical Mechanics
A uniform circular disc on the xy-plane with its centre at the origin has a moment of inertia I0 about the x-axis. If the disc is set in rotation about the origin with an angular velocity ω = ω0(ĵ + k̂), the direction of its angular momentum is along:
- 1ĵ + k̂
- 2ĵ + 2k̂✓
- 3-î + ĵ + 2k̂
- 4-î + ĵ + k̂
Correct answer
ĵ + 2k̂
