हिन्दीA body cools from a temperature \( 3T \) to \( 2T \) in 10 minutes. The room temperature is \( T \). Assume that Newton's law of cooling is applicable. The temperature of the body at the end of next 10 minutes will be
Correct answer · Option 4
\( \frac{4}{3}T \)
Explanation
Applying Newton's law of cooling \( \frac{dT}{dt} = -K(T - T_0) \), integrating between limits gives the ratio of temperature differences. For the next 10 minutes, the temperature decreases to \( \frac{4}{3}T \).
