Centripetal Force And Centrifugal Force - Practice Questions & MCQ

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/F₂  is ,

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  rotates around a horizontal circle at a speed of and a attached to the end of a rope   1m long. What is the centripetal acceleration of the stone?

A stone of mass is tied to end of a massless string of length .If the breaking tension of the string is , then maximum linear velocity, the stone can have without breaking the string, while rotating in horizontal plane, is :
