Question

A simple pendulum whose time period is T,
is suspended from roof of a lift. The lift
starts moving with an upward acceleration
of g/4. The new time period of the simple
pendulum is​

Answer 1

Answer:

T=2π1gl

Inside the moving lift

T=2π1g+al

hence T will decrease.

Answer 2

Answer:T'=√1/4 T

Explanation:

Take T=2π√ l/g now since you are calculateing new timeperiod name new timeperiod T' now use the formula T'=2π√ l/g/4 (replacing g by g/4) now get 4 aside like this T'=2π√ l/g . √1/4 now

as T=2π√ l/g

adding the value of T

the equation will look like

T'=√1/4 T
