Question

A particle is revolving in a circular path completes first one third of circumference in 2 sec. while next one third in 1 sec. calculate avg vel of particle.

Answer 1

for circle we know
2πr/t
the circumference is given
=2/1
=2ms^1

Answer 2

It should be 4π/9

As angular displace ment of particle should be 2π/3 for both case and if we divide it by time we get the ans
