2072 Set D Q.No. 9 A stone with mass 0.8 kg is attached to
one end of a string 0.9 m long. The string will break if its
tension exceeds 600 N. The stone is whirled in a horizontal
circle, the other end of the string remains fixed. Find the
maximum speed, the stone can attain without breaking the
string.

Answer:

v<26m/s

Explanation:

Mass = 0.8 kg

Radius = 0.9 m

As we know, the centripetal force acting on a body attached to a string is due to the Tension

Thus,

\frac{mv^2}{r} &lt;600\\\\i.e., \frac{0.8(v^2)}{0.9} &lt;600\\i.e., v^2&lt;675\\Thus, v&lt; 25.98  m/s\\Hence, v&lt; 26 m/s
