Question

time period of Pendulum is 4 seconds find its length given G is equal to 10 metre per second square​

Answer 1

Answer:

hey dude i think it is correct ans.

Explanation:

T=4s

T=2π√l/g

l=length of pendulum

T=time period

g=acceleration due to gravity

thus,

T*2=4π*2 l/g

l=T*2 g/4π*2

=4*2(10)/4(3.14)*2

=16(10)/39.43

=60/39.43

=1.52 m

hope this is right ans.. dude i try it but don't sure
