In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
Answer: The end point of a spring oscillates with a period of 2.0 s when a block with mass m is attached to it. When this mass is increased by 2.0 kg, the period is found to be 3.0 s. Then the mass m is 0.625kg.
Explanation: To find the answer, we need to know more about the simple harmonic motion.
<h3>
What is simple harmonic motion?</h3>
- A particle is said to execute SHM, if it moves to and fro about the mean position under the action of restoring force.
- We have the equation of time period of a SHM as,
![T=2\pi \sqrt{\frac{m}{k} }](https://tex.z-dn.net/?f=T%3D2%5Cpi%20%5Csqrt%7B%5Cfrac%7Bm%7D%7Bk%7D%20%7D)
- Where, m is the mass of the body and k is the spring constant.
<h3>How to solve the problem?</h3>
![T_1=2s\\m_1=m\\m_2=m+2kg\\T_2=3s](https://tex.z-dn.net/?f=T_1%3D2s%5C%5Cm_1%3Dm%5C%5Cm_2%3Dm%2B2kg%5C%5CT_2%3D3s)
- We have to find the value of m,
![T_1=2\pi \sqrt{\frac{m}{k} } \\T_2=2\pi \sqrt{\frac{m+2}{k} } \\\frac{T_1}{T_2} =\sqrt{\frac{m}{m+2} }\\\frac{2}{3} =\sqrt{\frac{m}{m+2} }\\\\](https://tex.z-dn.net/?f=T_1%3D2%5Cpi%20%5Csqrt%7B%5Cfrac%7Bm%7D%7Bk%7D%20%7D%20%5C%5CT_2%3D2%5Cpi%20%5Csqrt%7B%5Cfrac%7Bm%2B2%7D%7Bk%7D%20%7D%20%5C%5C%5Cfrac%7BT_1%7D%7BT_2%7D%20%3D%5Csqrt%7B%5Cfrac%7Bm%7D%7Bm%2B2%7D%20%7D%5C%5C%5Cfrac%7B2%7D%7B3%7D%20%3D%5Csqrt%7B%5Cfrac%7Bm%7D%7Bm%2B2%7D%20%7D%5C%5C%5C%5C)
![m=\frac{5}{8} =0.625kg](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B5%7D%7B8%7D%20%3D0.625kg)
Thus, we can conclude that, the mass m will be 0.625kg.
