Time Period of a Simple Pendulum in a Freely Falling Lift will be​

Answer 1

${\huge{\boxed{\tt{\color {red}{Answer❀✿°᭄}}}}}$

During free fall the body feels weightless inside the lift. Hence, the time period of a simple pendulum in a freely falling lift will be infite(∞).

Answer 2

EXPLAINATION

Formula for Time Period

Time period, t = 2π √(t/g)

Where

• t → time period
• g → acceleration due to gravity

During free fall the body feels weightless inside the lift or no Acceleration will be acting on the body So, g = 0

NOW

∴ Time period, t

• = 2π √(t/0)
• = 2π √∞
• = ∞

Thus, the time period of a simple pendulum in a freely falling lift will be infinity (∞).
