A simple pendulum was given to a physics student to determine its time period. Arrange the following steps in sequential order to determine its time period.
(A). Calculate the radius of the bob 'R' by divding the diameter by 2.
(B) Take a metre scale and measure the length of the string from the point of suspension to the lower tip of the bob `(l_(1))`
(C). Place the bob over a meter scale and hold it in postion with two wooden blocks of stiff cadboards. Measure the diamter (D)of the bob.
(D). NOW, the length of the pendulum `(l)` is given by ` (l_(1) -R)`
E. Consider the formula ` T= 2pi. sqrt(l/g)` calculate.
The time period of the simple pendulum.
