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,

A conical pendulum of length 1 m makes an angle  $\theta=45^{\circ}$ w.r.t. Z-axis and moves in a circle in the XY plane.  The radius of the circle is 0.4 m and its center is vertically below O.  The speed of the pendulum (in m/s), in its circular path, will be : (Take g=10 ms⁻²)

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 car starts moving in a circular path of a radius of 200 m. Its speed is increasing at the rate of $2 \mathrm{~m} / \mathrm{s}^2$. The acceleration of the car after 20 seconds of starting motion is 

A particle is going from point A to B in a circular path. The ratio of distance and displacement 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 1 kg is tied to end of a massless string of length 1 m. If the breaking tension of the string is 400 N, then maximum linear velocity, the stone can have without breaking the string, while rotating in horizontal plane, is :
