A stone of mass of 16 kg is attached to a string 144 m long and is whirled in a horizontal smooth surface. The maximum tension the string can withstand is 16 newton. The maximum speed of revolution of the stone without breaking it, will be :
  • a)
    20 ms-1
  • b)
    16 ms-1
  • c)
    14 ms-1
  • d)
    12 ms-1
Correct answer is option 'A,C,D'. Can you explain this answer?

Analysis:
The stone is undergoing circular motion in a horizontal plane with a maximum tension of 16 N.

Centripetal Force:
The tension in the string provides the centripetal force required to keep the stone in circular motion.

Centripetal Force Formula:
\( F_{\text{centripetal}} = \frac{mv^2}{r} \)

Maximum Tension:
The maximum tension the string can withstand is 16 N.

Calculations:
Given mass, m = 16 kg
Length of the string, r = 144 m
Maximum tension, T = 16 N

Maximum Speed:
- Using the formula for centripetal force, we can find the maximum speed of revolution without breaking the string.
- \( T = \frac{m v^2}{r} \)
- \( v^2 = \frac{T \cdot r}{m} \)
- \( v^2 = \frac{16 \cdot 144}{16} \)
- \( v^2 = 144 \)
- \( v = \sqrt{144} \)
- \( v = 12 \, \text{ms}^{-1} \)
Therefore, the maximum speed of revolution of the stone without breaking the string is 12 ms-1.
