Due to rotation of the earth the direction of vertical at a place is not along the radius of the earth and actually makes a small angle phi with the true vertical (i.e. with radius). At hat latitude theta is this angle phi maximum ?

The Earth is an oblate spheroid and not a perfect sphere. This is because 1. the Earth has a rotational motion and the rotational speed increases as one goes from the Poles towards the Equator. 2. the Equator experiences greater gravitational pull from the Sun. 3. the intensity of sunlight received at the Equator is greater than that at the Poles. Select the correct answer using the code given below:

A satellite ils launched into a circular orbit 1600km above the surface of the earth. Find the period of revolution if the radius of the earth is R=6400km and the acceleration due to gravity is 9.8ms^(-2) . At what height from the ground should it be launched so that it may appear stationary over a point on the earth's equator?

Considering the earth to be a perfect sphere of radius 6.4 xx 10^(6)m , rotating about its axis with a period of 1 day (= 8.64 xx 10^(4)s) , calculate the difference in acceleration due to gravity at the poles and the equator.

Angular speed of rotation of the earth is omega_(0). A train is running along the equator at a speed v from west to east. A very sensitive balance inside the train shows the weight of n object as W_(1). During the return journey when the train is running atsame speed from east to west the balance shows the weight of the object to be W_(2). Weight of the object when the train is at rest was shown to be W_(0) by the balance. Calculate W_(2) – W_(1).

The earth's magnetic field may be considered to be due to a short magnet placed at the centre of the earth annd oriented along the magnetic south-north direction. The ratio of the magnitude of the magnetic field on the earth's magnetic equator to that at the magnetic poles is

A pendulum having a bob of mas 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 tehstring is T_0 . a. Find the speed of the shp due to rotation of the earth about its axis. b. find the differecne between T_0 and th 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 omega and radius of the earth is R.
