A simple pendulum made of a bob of mass m and a metallic wire of negligible mass has time period 2s at T= 0^(@)C. If the temperature off the wire is increased and the corresponding change in its time period is plotted angainst its temperature, the resulting graph is a line of slope S. If the coefficient of linear expansion of metal is alpha then the value of S is :

1.	A simple pendulum made of a bob of mass m and a metallic wire of negligible mass has time period 2s at T= 0^(@)C. If the temperature off the wire is increased and the corresponding change in its time period is plotted angainst its temperature, the resulting graph is a line of slope S. If the coefficient of linear expansion of metal is alpha then the value of S is :
Answer» `(ALPHA)/(2)` `2 alpha` `alpha` `(1)/(alpha)` ANSWER :C
