The apparent weight of an object increases in an elevator while accelerating upward. A moongphaliwala sells his moongphali usinga beam balance in an elevator. Will he gain more if the elevator is accelerating up?

A barometer kept in an elevator accelerating upward reads 76 cm. The air pressure in the elevator is

(A) : The apparent weight of a body in an elevator moving with some downward acceleration is always less than the actual weight of body. (R) : Normal reaction force by the floor of elevator on the body is less than the weight of the body when elevator is moving down

A spring of spring constant 200 N//m has a block of mass 1 kg hanging at its one end and form the other and the spring is attached to a ceiling of an elevator. The elevator rises upwards with an acceleration of g//3 . When acceleration is suddenly ceased , then what should be the angular frequency and elongation during the time when the elevator is accelerating?

Is Archimedes principle valid in an elevator accelerting up? In a car accelerating on a level road?

Assertion : The apparent weight of a body in an elevator moving with some downward acceleration is less than the actual weight of body. Reason : The part of the weight is spent in producing downward acceleration, when body is in elevator.

A person is standing in an elevator. In which situation he finds his weight less ?

A spring of force constant 200Nm^(-1) has a block of mass 10 kg hanging at its one end and the other end of the spring is attached to the celling of an elevator. The elevator is rising upwards with an acceleration of g/4 and the block is in equilibrium with respect to the elevator . when the acceleration of the elevator suddenly ceases , the block starts oscillating . What is the amplitude (in m) of these oscillations ?

A stone is released from an elevator going up with an acceleration a. The acceleration of the stone after the release is

A block with a mass of 2 kg hangs without vibrating at the end of a spring of spring constant 500N//m , which is attached to the ceiling of an elevator. The elevator is moving upwards with an acceleration (g)/(3) . At time t = 0 , the acceleration suddenly ceases. (a) What is the angular frequency of oscillation of the block after the acceleration ceases ? (b) By what amount is the spring stretched during the time when the elevator is accelerating ? (c )What is the amplitude of oscillation and initial phase angle observed by a rider in the elevator in the equation, x = Asin (omega t + phi) ? Take the upward direction to be positive. Take g = 10.0 m//s^(2) .

A man (mass =50 kg) is in an elevtor with is moving with acceleration 0.49 m//s^(2) upwards. Find normal reaction exerted by man on floor of the elevator.
