Two satellites going in equatoral plane have almost same radii. As seen from the earth one moves from east to west and the other from west to east. Will they hav the same time period as seen from the earth? If not which on will have less time period?

A satellite A of mass m is at a distance of r from the surface of the earth. Another satellite B of mass 2m is at a distance of 2r from the earth's centre. Their time periods are in the ratio of

A person moves 30m north and then 20 m towards east and finally 30sqrt(2) m in south-west direction. The displacement of the person from the origin will be

The time period of mass suspended from a spring is T. If the spring is cut into four equal parts and the same mass is suspended from one of the parts, then the new time period will be…….

Calculate the distance from the surface of the earth at which acceleration due to gravity is the same as below and above the earth

Near the earth's surface time period of a satellite is 4 hrs. Find its time period if it is at the distance '4R' from the centre of earth :-

A constant current I flows in a horizontal wire in the plane of paper from east to west as shown in the following figure : At which poit will the direction of the magnetic field be from north to south ?

A satellite is seen after every 8 hours over the equator at a place on the earth when its sense of rotation is opposite to the earth. The time interval after which it can be seen at the same place when the sense of rotation of earth and satellite is same will be:

One projectile after deviating from its path starts moving round the earth in a circular path of radius equal to nine times the radius of earth R. Its time period is

A satellite moves eastwards very near the surface of the Earth in equitorial plane with speed (v_(0)) . Another satellite moves at the same height with the same speed in the equatorial plane but westwards. If R =radius of the Earth and omega be its angular speed of the Earth about its own axis. Then find the approximate difference in the two time period as observed on the earth.
