A uniform metal rod (bar pendulum), which is coefficient of linear expansion is

2 \times 10^{-6} /{ }^{\circ} \mathrm{C}

, the period of the pendulum will have percentage increase, if room temperature rise by

10^{\circ} \mathrm{C}

View answer and explanation

Correct option: C

10^{-3} \%

Option C (

10^{-3} \\%

) is correct because it accurately calculates the percentage increase in the period of the pendulum due to the temperature rise.
