92. A pendulum having a bob of mass m is hanging in a ship sailing along the equator from east to west. When the ship is stationary with respect to water the tension in the string is T . (a) Find the speed of the ship due to rotation of the earth about its axis . (B) Find the difference between T and the earths attraction on the Bob. (C) If the ship sails at speed V , what is the tension in the string ? Angular speed of earths rotation is omega (w) and radius of the earth is R.
