A pendulum is made to hang from the ceiling of an elevator. It has period of T s (for small angles). The elevator is made to accelerate upwards with `10 m//s^(2)`. The period of the pendulum now will be (assume `g=10m//s^(2)`)

A

`Tsqrt2`

B

Infinite

C

`T//sqrt2`

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
C

`g_("eff")=g+a=10+10=20m//s^(2)`
`T.=2pisqrt((l)/(g.)) implies T.=(T)/(sqrt2)`.
