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.
