Vertical Circular Motion

A stone of mass $1 \mathrm{kg}$ is tied with a string, and it is whirled in a vertical circle of radius $1 \mathrm{m}.$ If tension at the highest point is $14 \mathrm{N},$then velocity at lowest point will be

A particle of mass $200 \mathrm{g},$ is whirled into a vertical circle of radius $80 \mathrm{cm}$ using a massless string. The speed of the particle when the string makes an angle of $60°$ with the vertical line is $1.5 \mathrm{m}{\mathrm{s}}^{-1}$. The tension in the string at this position is

A particle of mass $200 \mathrm{g}$ is moving in a circle of radius $2 \mathrm{m}.$ The particle is just 'looping the loop'. The speed of the particle and the tension in the string at highest point of the circular path are $\left(\mathrm{g}=10{ \mathrm{ms}}^{-2}\right)$

When a particle connected with string moves in a vertical circle, then tension is maximum at _____ point.

A particle is moving along a vertical circle of radius $R.$ At $P,$ what will be the velocity of particle (assume critical condition at $C) ?$

A stone of mass $2 \mathrm{kg}$ tie with the help of thread of length $2 \mathrm{m}$ and moves in vertical circle of radius $2 \mathrm{m}$ and moves in vertical circular motion. The difference between tension in the thread at lowest point and at the highest point is (Take $g=10 \mathrm{m} {\mathrm{s}}^2)$
