Question

In order to check the speed of a camera shutter, the camera was used to photograph the bob of a

simple pendulum moving in front of a horizontal scale. The extreme positions of the bob were at

the 600 mm and 700 mm marks. The photograph showed that while the shutter was open the bob

moved from the 650 mm mark to the 675 mm mark. If the period of the pendulum was 2 s,

calculate the time length for which the shutter remained open.​
