Let the angular velocity of the particle about centre c = ωc,

and at point A on the circumference of circle = ωawe know that angular velocity about centre of circle =2 times about angular velocity about any point on the circumference. 

ωc = 2 ωa 

ωa/ωc   =  1/2

hence 2 is correct option.

Answer 2

Answer:

Let the angular velocity of the particle about centre c = ωc,

and at point A on the circumference of circle = ωawe know that angular velocity about centre of circle =2 times about angular velocity about any point on the circumference.

ωc = 2 ωa

ωa/ωc = 1/2

hence 2 is correct
