Time period of a pendulum in a elevator at rest is T. Calculate the - period of pendulum if the lift is moving upward with the acceleration` g/3`

The time period of a seconds pendulum is

Time period of a simple pendulum is 2 s. If its length is doubled, then the new time period will be

A person of mass m is standing in a lift. Find his apparent weight when the lift is (i) moving upwards with uniform acceleration a,

A lift of mass 400 kg is hung by a wire. Calculate the tension in the wire when the lift is (a) at rest, (b) moving upward with a constant acceleration of 2.0 m//s^(2) and (c) moving downward with an acceleration 2.0 m//s^(2) .

The errors in the measurement of the effective length ( l ) and the time period (T) of a pendulum executing simple harmonic motion are 1% and 2% respectively. Estimate the error in the determination of acceleration due to gravity (g) using this pendulum. Given the relation among the relevant quantities, T = 2pi sqrt((l)/(g)).
