A magnetic needle suspended by a silk thread is vibrating in the earth...
Explanation:
Effect of temperature on the magnetic needle suspended by a silk thread can be explained by the following points:
1. Magnetic susceptibility of the needle decreases with an increase in temperature.
2. The strength of the magnetic field decreases with an increase in temperature.
3. The moment of inertia of the needle increases with an increase in temperature.
Based on the above points, the effect of temperature on the time period of vibration of the needle can be understood as follows:
1. The decrease in magnetic susceptibility leads to a decrease in the strength of the restoring force acting on the needle. This results in an increase in the time period of vibration.
2. The decrease in the strength of the magnetic field also leads to a decrease in the restoring force acting on the needle. This again results in an increase in the time period of vibration.
3. The increase in moment of inertia leads to an increase in the time period of vibration.
Therefore, the time period of vibration of the magnetic needle suspended by a silk thread remains unchanged when the temperature is increased by 700oC.
Answer: Option D. Time period increases.
