Question

Bob of a simple pendulum takes 1.25 seconds to go from one extreme position to other extreme position calculate the time period of the pendulum

Answer 1

Answer:

2.5 secs

Explanation:

Bob of a simple pendulum takes 1.25 seconds to go from one extreme position to other extreme position calculate the time period of the pendulum

time period of the pendulum is to and fro time from one extreme position to other extreme position

time taken from one extreme position to other extreme position = 1.25 secs

time taken to & from from one extreme position to other extreme position = 2 * 1.25 = 2.5 secs

Answer 2

answer : 2.50 sec

explanation : Time period is the time taken by particle to complete one oscillation.

in case of pendulum, time taken to complete to-and-fro motion.

see figure, from R to S and back to R is one complete oscillation.

here given, time taken to one extreme position to another extreme position is 1.25 s

for better understanding, we can say time is given to move from R to S is 1.25s

so, time period = 2 × time taken to move from R to S = 2 × 1.25 s

= 2.5 sec

hence, time period of pendulum is 2.5 sec
