A particle of mass M is moving in a horizontal circle of radius R with uniform speed V. When it moves from one point to a diametrically opposite point, its
A ball of mass 0.1 Kg. is whirled in a horizontal circle of radius 1 m. by means of a string at an initial speed of 10 R.P.M. Keeping the radius constant, the tension in the string is reduced to one quarter of its initial value. The new speed is
A cyclist riding the bicycle at a speed of \[14\sqrt 3 \] ms–1 takes a turn around a circular road of radius \[20\sqrt 3 \] m without skidding. Given $g = 9.8 ms^{–2}$, what is his inclination to the vertical
If a cycle wheel of radius 4 m completes one revolution in two seconds. Then acceleration of a point on the cycle wheel will be
A bob of mass 10 kg is attached to wire 0.3 m long. Its breaking stress is $4.8 \times 10^7 N/m^2$. The area of cross section of the wire is $10^{–6} m^2$. The maximum angular velocity with which it can be rotated in a horizontal circle
In uniform circular motion, the velocity vector and acceleration vector are
If a cyclist moving with a speed of 4.9 m/s on a level road can take a sharp circular turn of radius 4 m, then coefficient of friction between the cycle tyres and road is
