A vehicle of mass 5000 Kg starts taking a circular turn of radius 10 m. The initial speed of the vehicle on a circular track is 5 $\mathrm{m} / \mathrm{s}$ and it is increasing with the rate of $1 \mathrm{~m} / \mathrm{s}^2$. After how much time the vehicle will be just about to overturn [Assume distance between two vehicle $=4 \mathrm{~m}$, the height of the center of mass of vehicle $=2 \mathrm{~m}, \mathrm{~g}=10 \mathrm{~m} / \mathrm{s}^2$ ]
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 :

Centripetal Force-
-
Force acts on the body along the radius and towards the center.

$
\begin{aligned}
& F=4 m \pi^2 n^2 r \\
& F=\frac{4 m \pi^2 n^2 r}{T^2}
\end{aligned}

Where
$\mathrm{F}=$ Centripetal force
$\omega=$ Angular velocity
$\mathrm{n}=$ frequency
-
Centrifugal Force
-
It is a fictitious force which has significance only in the rotating frame of reference.
-
It is an Imaginary force due to incorporated effects of inertia.
