Expression for centripetal acceleration
Asked by pratikbharadia | 06 Aug, 2008, 05:25: PM
answered-by-expert Expert Answer

The centripetal force is the external force required to make a body follow a curved path.This force has the magnitude  F = mv^2/ r.

 

Here the acceleration in circular motion is called centripetal (centre-seeking) acceleration as it is always directed towards the centre of the circle.

Force = mass X acceleration = m ( v^2 / r) , where m= mass of the body v=its velocity , r=radius of the circle

Two blocks of mass m=5kg and M=10 kg are connected by a string passing over a pulley B as shown. Another string connects the centre of the pulley B to the floor and passes over another pulley A as shown. An upward force F is applied at the centre of pulley A. Both the pulleys are massless. Find the acceleration of both the blocks if 1) F=100N.  2)F=500N

In the arrangement shown in the figure, a heavy pulley of mass M is suspended from a spring of stiffness constant K and the mass m is suspended from a string tightly wound on the pulley. If the mass m is given a small downward displacement and released, find the time period of small oscillations (Take pulley as Disc) and string does not slips on the pulley.
