PhysicsEasysingle choice

A particle of mass $100 g$ tied to a string is rotated along the circle of radius $0.5 m$ . The breaking tension of the string is $10 N$ . The maximum speed with which particle can be rotated without breaking the string is

Options:

Answer:

Solution:

$F = m ω^{2} r = \frac{m v^{2}}{r}$

$v = \sqrt{\frac{f . r}{m}} = \sqrt{\frac{10 \times 0.5}{100 \times 1 0^{- 3}}} m s^{- 1}$

$= 7.07 m s^{- 1}$
