Question

The period of simple pendulum is measured as T in a stationary lift. If the lift moves upward with an acceleration of 5 g, the period will ____________.

Options

• remain same

• increase by `3/5`

• decrease by `2/3` times

• none of above

Answer 1

The period of simple pendulum is measured as T in a stationary lift. If the lift moves upward with an acceleration of 5 g, the period will none of above.

Explanation:

`"T" = 2pi sqrt(l/"g") Rightarrow "T'"`

` = 2pi sqrt(l/("g" + 5"g"))`

` = "T"/sqrt6`
