The diagram shows a cup of tea seen from above. The tea has been stirred and is now rotating without turbulence. A graph showing the speed `v` with which the liquid is crossing points at a distance `X` from `O` along a radius `OX` would took like

Figure shows a cross section of a large metal. Sheet carrying an electric current along its surface. The current in a strip of width dl is Kdl where K is a constant. Find the magnetic field at a point P at a distance x from the metal sheet.

The figure shows a system consisting of (i) a ring the outer radius 3R rolling clockwise without slipping on a horizontal surface with angular speed omega and (ii) an inner disc of radius 2R rotating anti clockwise with angular speed omega//2. The ring and disc are separted. The point P on the inner disc is at a distance R from the origin, where OP makes an angle of 30^@ with the horizontal. Then with respect to the horizontal surface,

The following diagram shows the electric field lines between two opposite charges. The positive charge is indicated by the black circle, the negative charge by the white circle. An electron string from rest at the indicated position (X) , and accelerated to high speed by the electric field will follow most likely which trajectory?
