A stone of mass $0.3 kg$ attached to a $1.5 m$ long string is whirled around in a horizontal circle at a speed of $6 m / s$ . The tension in the string is

Options:

Answer:

Solution:

The force of tension in the string provides required centripetal force to keep the stone in circular motion.

$∴ T = \frac{m υ^{2}}{R} = \frac{0.3 \times {(6)}^{2}}{1.5} = 7.2 N$
