I want to know how to solve the below question
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 'T0' . (a) Find the speed of the ship due to the rotation of the earth about it's axis. (b) Find the difference between 'T0' and the earth's attraction on the bob. (c) If the ship sails at speed v , what is the tension in the string? Angular speed of earth's rotation is w and the radius of the earth is R.
please get me the solved out part of this sum .....
Thank you.
