If T = 2pi sqrt(l/g) is the time period ...

If `T = 2pi sqrt(l/g)` is the time period of a simple pendulu, then the unit of `4pi^(2) l/T^(2)` in the SI system is ________ .

A

`m s^(-1)`

B

` s^(-2)`

C

`m s^(-2)`

D

`s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
From the figure:
The distance moved by the body = 20 m
The time taken to trace the path , (t) = 10s
(1) The average speed=` (" total distance")/("total time")`
` 20/10 = 2 ms ^(-1)`

Show that the time period of a simplw pendulam of infinite length is given by t=2pi sqrt((R)/(g)) where R is the radius of the earth

A student measures the value of g with the help of a simple pendulum using the formula g = (4pi^(2)L)/(T^(2)) . He measures length L with a meter scale having least count 1 mm and finds it 98.0 cm . The time period is measured with the help of a watch of least count 0.1s . The time of 20 oscillations is found to be 40.4 s. The error Deltag in the measurment of g is (" in" m//s^(2)) .
