Question: Two particles A and B of masses m1 and m2 are moving in a circular path with angular velocities ω1 and ω2 respectively. What is the total angular momentum of the system?

Options:

  1. m1ω1 + m2ω2
  2. m1ω1 - m2ω2
  3. m1ω1m2ω2
  4. m1ω1 + m2ω2/2

Correct Answer: m1ω1 + m2ω2

Solution: 

Total angular momentum L = m1ω1 + m2ω2 for particles moving in the same direction.

Questions & Step-by-Step Solutions

Two particles A and B of masses m1 and m2 are moving in a circular path with angular velocities ω1 and ω2 respectively. What is the total angular momentum of the system?
  • Step 1: Understand that angular momentum is a measure of how much motion an object has while rotating.
  • Step 2: Identify the two particles A and B with their respective masses m1 and m2.
  • Step 3: Note the angular velocities of the particles, which are ω1 for particle A and ω2 for particle B.
  • Step 4: Recognize that if both particles are moving in the same direction, their angular momenta can be added together.
  • Step 5: Calculate the angular momentum of particle A using the formula: L1 = m1 * ω1.
  • Step 6: Calculate the angular momentum of particle B using the formula: L2 = m2 * ω2.
  • Step 7: Add the angular momenta of both particles to find the total angular momentum: L = L1 + L2 = m1 * ω1 + m2 * ω2.
