Question

Arod of mass mand length Lis in horizontal position which is hinged at point P.And free to
rotate in vertical plane. Particles of mass 2m are continuously colliding to the rod with a
speed vat a rate of n number of particles per sec as shown in figure. After collision particles
comes to rest. Rod is in equilibrium then nis
L/4​

Answer 1

Explanation:

mul=( 3ml × 2+ml /2 )ω

Where,

m is mass

u is initial speed

l is length

ω is angular velocity

That is,

Angular velocity, ω=

3a/ 4l
