A body is suspended on a spring balance ...

A body is suspended on a spring balance in a ship sailing along the equator with a speed `v`. Show that the scale reading will be very close to `W_(0)(1 pm (2 omega v)/(g))`, where `omega` is the angular speed of the earth and `W_(0)` is the reading of spring balance when the ship is at rest. Explain the plus or minus sign
[Hint : `W_(0)=mg-momega^(2)R,W=mg-m((momega+v)^(2))/(R)` when the ship is moving from west to east]

A body suspended on a spring balance in a ship weighs W_(0) when the ship is at rest. When the ship begins to move along the equator with a speed v , show that the scale reading is very close to W_(0) (1+-2omegaV//g ), where omega is the angular speed of the earth.

A body is suspended on a spring balance in a ship sailing along the equator with a speed v'. If omega is the angular speed of the earth and omega_(0) is the scale reading when the ship is at rest, the scale reading when the ship is sailing is

A body is weighed with a spring balance in a train at rest, shown a weight W . When the train begins to move with a velocity upsilon around the equator from west to east and if the angular velocity of the train is omega then the weight shown by spring balance is

A body is suspended from a spring balance kept in a satellite. The reading of the balance is W_1 when the satellite goes in an orbit of radius R and is W_2 when it goes in an orbit of radius 2R.

What will be the reading of spring balance in the figure shown in following situations ( g = 10 m//s^(2) ) a= 0, v = 0

An object weights W newton on earth. It is suspended from the lower end of a spring balance whose upper end is fixed to the ceiling of a space capsule in a stable orbit around the earth. The reading of the spring balance will be

A block of weight W is suspended from a spring balance. The lower surface of the block rests on a weighing mechine. The spring balance reads W_(1) and the weighing machine reads W_(2)(W,W_(1),W_(2) are in the same unit).

A weight is suspended from the ceiling of a lift by a spring balance. When the lift is stationary the spring balance reads W . If the lift suddenly falls freely under gravity, the reading on the spring balance will be
