Assertion :- A particle on earth found to be at rest when seen from a frame U_(1) and moving with a constant velocity when seen from another frame U_(2) . Then both frames may be non - inertial. Reason :- A reference frame attached to the earth must be an inertial frame.

A refrence frame attached to the earth

(A) : A reference frame attached to earth is a non inertial frame of reference. (R) : The reference frame which has an acceleration is called a non inertial frame of reference.

Two satellites A and B of equal mass move in the equatorial plane of the earth, close to earth's surface. Satellite A moves in the same direction as the of the rotation of the earth while satellite B moves in the opposite direction. Calclate the ratio of the kinetic energy of B of that of A in the reference frame fixed to the earth (g=9.8ms^(-2) and radius of the earth =6.37xx10^(6)km)

(A):A balloon ascends from the surface of earth with constant speed.When it was at a height 50m above the ground,a packet is dropped from it .To an abserver on the balloon,the displacement of the packet,from the moment it is dropped to the moment it reaches the surface of earth is 50m. (R ):Displacement vector does not depend upon the reference frame used to measure it.
