As the length of the minute needle is 7cm
on 9 am the minute needle is on 12 and on 9 30 am
minute needle is on 6
so the displacement is the diameter of the semicircle formed by the minute hand
displacement 14 cm
on 9 am the minute needle is on 12 and on 9 30 am
minute needle is on 6
so the displacement is the diameter of the semicircle formed by the minute hand
