A body of mass 100 g is moving in a circular path of radius 2 m on a vertical plane as shown in the figure. The velocity of the body at point A is 10 m/s. The ratio of its kinetic energies at point B and C is: (Take acceleration due to gravity as 10 m/s$^2$)

A body of mass $100 \;g$ is moving in a circular path of radius $2\; m$ on a vertical plane as shown in the figure. The velocity of the body at point A is $10 m/s.$ The ratio of its kinetic energies at point B and C is: (Take acceleration due to gravity as $10 m/s^2$)

A sportsman runs around a circular track of radius $ r $ such that he traverses the path ABAB. The distance travelled and displacement, respectively, are:

A wheel is rolling on a plane surface. The speed of a particle on the highest point of the rim is 8 m/s. The speed of the particle on the rim of the wheel at the same level as the center of the wheel, will be:

A satellite of $ 10^3 \, \text{kg} $ mass is revolving in a circular orbit of radius $ 2R $. If \[ \frac{10^4 R}{6} \, \text{J} \] energy is supplied to the satellite, it would revolve in a new circular orbit of radius: \[ \text{(use } g = 10 \, \text{m/s}^2, \, R = \text{radius of earth)}. \]

If the radius of curvature of the path of two particles of the same mass are in the ratio $ 3:4 $, then in order to have constant centripetal force, their velocities will be in the ratio of:

A man carrying a monkey on his shoulder does cycling smoothly on a circular track of radius $ 9 \, \text{m} $ and completes $ 120 $ revolutions in $ 3 $ minutes. The magnitude of centripetal acceleration of the monkey is (in $ \text{m/s}^2 $):

A ball of mass 0.5 kg is attached to a string of length 50 cm. The ball is rotated on a horizontal circular path about its vertical axis. The maximum tension that the string can bear is 400 N. The maximum possible value of angular velocity of the ball in rad/s is,:

A particle is moving in a circle of radius 50 cm in such a way that at any instant the normal and tangential components of its acceleration are equal. If its speed at $ t = 0 $ is $ 4 \, \text{m/s} $, the time taken to complete the first revolution will be\[\frac{1}{\alpha} \left[ 1 - e^{2\pi} \right] \, \text{s},\]where $ \alpha = \, \underline{\hspace{2cm}} $.

A bob of mass $ m $ is suspended by a light string of length $ L $. It is imparted a minimum horizontal velocity at the lowest point $ A $ such that it just completes a half circle, reaching the topmost position $ B $. The ratio of kinetic energies $ \frac{(\text{K.E.})_A}{(\text{K.E.})_B} $ is:

A stone of mass 900 g is tied to a string and moved in a vertical circle of radius 1 m making 10 rpm. The tension in the string, when the stone is at the lowest point, is (if $ \pi^2 = 9.8 $ and $ g = 9.8 \, \text{m/s}^2 $)
