A $2 kg$ stone tied at the end of a string $1 m$ long is whirled along a vertical circle at a constant speed of $4 m s^{- 1}$ . The tension in the string has a value of $52 N$ when the stone is

Options:

Answer:

Solution:

Here, $m = 2 k g, r = 1 m, v = 4 m s^{- 1}$

Tension at the bottom of the circle,

$T_{L} = m g + \frac{m v^{2}}{r}$

$= 20 + \frac{2 \times 4^{2}}{1} = 52 N$
