Question

A particle of mass 1.6 x 10-27 kg is revolving on a circular path of radius 10cm under the
Influence of a centripetal force of 2.5 x 10-12. Find out the angular velocity?

Answer 1

I don't know if you've learned this equation:
F = m r w^2
where F=centripetal force, w = angular velocity
Assuming the force is in Newtons (you don't show the units), be sure to covert r = 10 cm to 0.1 m before solving.
