If the tension in the cable supporting an elevator is equal to the weight of the elevator, the elevator may be

The force exerted by the floor of an elevator on the foot of a person standing there is more than the weight of the person if the elevator is :

A person standing oin the floor of an elevator drops as coin. The coin reaches the floor of the elevator in a time t_1 if the elevator is stationary and in the t_2 if it is moving uniformly. Then

A collision experiment is done on a horizontal table kept in an elevator. Do you expect a change in the results if the elevator is accelerated up or down because of the noninertial character of the frame?

A man standing on a level plane observes the elevation of the top of a pole to be theta . He then walks a distance equal to double the height of the pole and then finds that the elevation is now 2theta . The value of cottheta is

A person is standing on a weighing machine placed on the floor of an elevator. The elevator starts going up with some acceleration, moves with uniform velocity for a while and finally decelerates to stop. The maximum and the minimum weights recorded are 72 kg and 60 kg. Assuming that the magnitudes of the acceleration and the deceleration are the same., find a. the true weight of the person and b. the magnitude of the acceleration. Take g=9.9 m/s^2 .

A simple pendulum of length l is suspended through the ceiling of an elevator. Find the time period of small oscillations if the elevator a. is going up with an acceleration a_0 . b. is going down with an acceleration a_0 and c. is moving with a uniform velocity.

A pendulum bobof masss 50 g is suspended from the ceiling of an elevator. Find the tension in the string if the elevator a. goes up with acceleration 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 downwith uniform velocity.
