Question
the angular momentum of a particle performing uniform circular motion is L. if the kinetic energy of particle is doubled and frequency is halved, then angular momentum becomes-
ans-4L
Read 1 Solution.
KE = 1/2 Iω2 = 1/2 Iωω = 1/2 L ω (ω = 2π/t = 2πf f is frequency)
now IF u double ke and if freq is halved then L WILL BECOMES 4 TIMES AS L IS DIRECTLY PROPORTIONAL TO KE / f FROM ABOVE EQN
