Two objects A and B are moving with velocities v_(A) and v_(B) respectively along positive x-axis. If v_(A) lt v_(B) then, which of the following position-time graphs is correctly showing the velocity of A and B ?

Two rough blocks A and B ,A placed over B move with acceleration veca_(A) and veca_(B) veclocities vecv(A) and vecv_(B) by the action of horizontal forces vec(F_(A)) and vec(F_(B)) , respectively. When no friction exsits between the blocks A and B,

Two frames of reference P and Q are moving relative to each other at constant velocity. Let vecv_(OP) and veca_(OP) represent the velocity and the acceleration respectively of a moving particle O as measured by an observer in frame P and vecV_(OQ) and veca_(OQ) represent the velocity and the acceleration respectively of the moving particle O as measured by an observer in frame Q , then

Force on a charged particle moving with velocity vecv subjected to a magnetic field is zero. This means:

The vector difference between the absolute velocities of two bodies is called their relative velocity. The concept of relative velocity enables us to treat one body as being at rest while the other is in motion with the relative velocity. This jormalism greatly simplifies many problems. If vecv_(A) is the absolute velocity of a body A and vec_(B) that of another body B then the relative velocity of A in relation to B is vec_(AD)=vecV_(A)-vecv_(B) and vecv_(BA)=vecv_(B) - vecv_(A) . The principle follows here is that the relative velocity of two bodies remains unchaged if the same additional velocity is imparted to both the bodies. A simple way of carrying out this operation is to be represent the velocities in magnitude and direction from a common point. Then the line joining the tips of the vectors represents the relative velocity Q A train A moves to the east with velocity of 40 km/hr and a train B moves due north with velocity of 30 km/hr. The relative velocity of A w.rt. B is

The velociies of A and B are vecv_(A)= 2hati + 4hatj and vecv_(B) = 3hati - 7hatj , velocity of B as observed by A is
