Questions
A particle performs uniform circular motion with an angular momentum L. If the angular frequency of the particle is doubled and kinetic energy is halved, its angular momentum becomes
detailed solution
Correct option is D
We know that, L=mωr2 Further, E=12Lω or L=2E/ω ∴ L′=E/22ω=E4ω=L4Talk to our academic expert!
