Questions
The Time period of oscillation of a simple pendulum whose length is very large (>> Radius of earth R) is T. What will be the time period of a simple pendulum whose length is equal to the radius of earth(R) ?
detailed solution
Correct option is D
For a pendulum whose length( l) is comparable to the radius of earth(R), time period is given byT = 2πg1l+1R If l >>R,T = 2πRg If l=R,T' = 2πR2g ∴T'T = 12 ⇒ T' = T2Talk to our academic expert!
