A cork is submerged in water by a spring attached to the bottom of a bowl. When the bowl is kept in an elevator moving with acceleration downwards, the length of spring.

A block is fully submerged in a vessel filled with water by a spring attached to the bottom of the vessel. In equilibrium position spring is compressed. If the vessel now moves downwards with an acceleration a(lt g) . What happens to the length of the spring.?

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 spring balance is attached to the ceiling of a lift. A man hangs his bag on the spring and the spring reads 49N, when the lift is stationary. If the lift moves downward with an acceleration of 5m//2^2 , the reading of the spring balance will be

An iron sphere is suspended with a spring. The length of the spring increases. When the sphere is completely in water, the extension in the length of the spring decreases. Why does it happen so?

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

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 celling 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 elongationduring the time when the elevator is accelerating?

One end of a spring of force constant k_1 is attached to the ceiling of an elevator. A block of mass 1.5kg is attached to the other end. Another spring of force constant k_2 is attached to the bottom of the mass and to the floor of the elevator as shown in figure. At equilibrium, the deformation in both the spring is equal and is 40cm . If the elevator moves with constant acceleration upward, the additional deformation in both the spring is 8cm . Find the elevator's accelerationn ( g=10ms^-2 ).

An engineer is designing a spring to be placed at the bottom of an elevator shaft, if the elevator cable should break at a height h above the top of the spring, calculate the required value of the spring constant k, so that passsengers undergo an acceleration of no more than 10 g when brought to rest, Let M be the total mass of the elevator and passengers
