A very long straight wire carries a constant current I0. In the dia-gram below, part (a) shows the side view of the wire, and part (b)shows the top view. Draw a neat vector that indicates the direction of the magnetic field at pointPon both views of the wire

their crystal patterns have been disrupted by stress

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
