A pendulum bob of mass 50 g is suspended from the ceiling of an elevator. Find the tension in the string if the elevator (a). goes up with acceleration of 1.2 m/`s^2`, (b). goes up with deceleration 1.2 m/`s^2`, (c). goes up with uniform velocity, (d). goes down with acceleration 1.2 m/`s^2` (e). goes down with deceleration 1.2 m/`s^2` and (f). goes down with uniform velocity.
