List of top Physics Questions on Circular motion asked in AP EAPCET

On imparting an initial velocity \(v_0\), a ball begins to move in horizontal circle of radius \(R\) on horizontal plane. If the coefficient of friction between the ball and plane is \(\mu\), then the time required by ball to come to rest is: center
center
A small bead is placed on a thin circular loop of radius \(25\,\text{cm}\) which is rotating about its vertical diameter with a constant velocity of \(10\,\text{rad s}^{-1}\). The angle made by the radius vector joining the center of the loop to the bead with the vertically downward direction is (Neglect friction and take \(g=10\,\text{m s}^{-2}\)):
A particle moves in a horizontal circle. If its speed is doubled, the centripetal force acting on it becomes:
A body of mass 1 kg is attached to one end of a string of 1 m length. It is rotated in a vertical circle with a constant speed of \( 4 \text{ ms}^{-1} \). When the object is at the highest point of the vertical circle, tension in the string is (\( g=10 \text{ ms}^{-2} \)):
A body of mass 1 kg is attached to one end of a string of 1 m length. It is rotated in a vertical circle with a constant speed of \( 4 \text{ ms}^{-1} \). When the object is at the highest point of the vertical circle, tension in the string is (\( g=10 \text{ ms}^{-2} \)):
A stone of mass $400\text{ g}$ tied to one end of a string is rotated in a horizontal circle of radius $125\text{ m}$. If the string can withstand a maximum tension of $50\pi^{2}\text{ N}$ then the minimum time period with which the stone can be rotated is
A bike race is conducted on a circular track of radius $60\text{ m}$. If the slowest bike, weighing $120\text{ kg}$, moved around the track at a constant speed of $108\text{ kmph}$, then the time taken by it to complete one lap and its acceleration are respectively
A particle is moving on a circular path with a constant speed \(v\). Its change of velocity as it moves from \(A\) to \(B\) in the figure is
A wheel is rotating freely at some angular speed. A second wheel initially at rest and with thrice the rotational inertia of the first, is suddenly coupled to the first wheel. The fraction of the original rotational kinetic energy lost is
A particle attached to a string of length \(r\) is moving on a vertical circular path continuously. If the speed of the particle at the highest point is \[ \sqrt{7gr}, \] then the ratio of the respective tensions in the string holding it at the highest and the lowest points is
The coefficient of static friction between the road and tyres of a car is \(0.4\). The maximum permissible speed of the car is \(10\text{ ms}^{-1}\) on a curved unbanked road. Then the maximum radius of curvature of the road is
\[ \text{(acceleration due to gravity }=10\text{ ms}^{-2}\text{)} \]
