Assertion : A geostationary satellite rotates in a direction from west to east.
Reason : At midnight when the sun is directly below. It pulls on an object in the same direction as the pull of the earth on that object. At noon when the sun is directly above. Its pulls on an object in a direction opposite to the pull of the earth.

A

B

If both Assertion & Reason are true but Reason is not a correct explanation of the Assertion.

C

If Assertion is True but the reason is False.

D

An astronaut of mass m is working on a satellite orbitting the earth at a distance h from the earth's surface the radius fo the earth is R while its mass is M the gravitational pull F_(G) on the astronaut is

Solve the follwing example . A current through a horizontal power line flows in east to west direction . What is the direction of magnetic field at a point directly below it and at a point directly above it ?

A short bar magnet placed in a horizontal plane has its axis aligned along the magnetic north-south direction. Null points are found on the axis of the magnet at 14 cm from the centre of the magnet. The earth's magnetic Meld at the place is 0.36 G and the angle of dip 18 zero. What is the total magnetic feld on the normal bisector of the magnet at the same distance as the mull-point (i.e., 14 cm) from the centre of the magnet? At rull points, field due to a magnet 1s equal and opposite to the horizontal component of earth's magnetic field.)

Two satellites of same mass m are revolving round of earth (mass M) in the same orbit of radius r. Rotational directions of the two are opposite therefore, they can collide. Total mechanical energy of the system (both satallites and earths) is (m lt lt M) :-

An object A is kept fixed at the point x= 3 m and y = 1.25 m on a plank p raised above the ground . At time t = 0 the plank starts moving along the +x direction with an acceleration 1.5 m//s^(2) . At the same instant a stone is projected from the origin with a velocity vec(u) as shown . A stationary person on the ground observes the stone hitting the object during its downward motion at an angle 45(@) to the horizontal . All the motions are in the X -Y plane . Find vec(u) and the time after which the stone hits the object . Take g = 10 m//s
