Solve by difficulty

An annular ring with inner and outer radii  R1 and R2 is rolling without slipping with a uniform angular speed. The ratio of the forces experienced by the two particles situated on the inner and outer parts of the ring ,F1/Fis ,

Two cars of masses m1 and m2 are moving in circles of radii r1 and r2 respectively. Their speeds are such that they make complete circles in the same time t. The ratio of their centripetal acceleration is:

A stone with a mass of  150\ g rotates around a horizontal circle at a speed of 10\ \frac{m}{s} and a attached to the end of a rope   1m long. What is the centripetal acceleration of the stone?

A stone of mass 1 \mathrm{~kg} is tied to end of a massless string of length 1 \mathrm{~m}.If the breaking tension of the string is 400 \mathrm{~N}, then maximum linear velocity, the stone can have without breaking the string, while rotating in horizontal plane, is :

Concepts Covered - 1

Centripetal Force and Centrifugal Force
  1. Centripetal Force-

  • Force acts on the body along the radius and towards the center.

    

F=4m\pi^{2}n^{2}r

F=\frac {4m\pi^{2}n^{2}r} {T^{2}} 

Where

F = Centripetal force

\omega= Angular velocity

n = frequency

  1. Centrifugal Force  

  • It is a fictitious force which has significance only in the rotating frame of reference.

  • It is an Imaginary force due to incorporated effects of inertia.
