A beam of electrons is accelerated from rest through a potential difference of 2 kV and passes between the plates of area 30 cm? and separation 9 mm as shown in the figure. If there is 2 mT perpendicular magnetic field at the region of plates directed out of the page, a) What must be the polarities of a and b so that electrons pass between the plates undeflected? b) By assuming that the plates form a parallel plate capacitor, calculate total charge of the plates? a

Newton's First Law of Motion

If a very smooth ball is rolled down an inclined surface with zero friction, the ball will continue to roll indefinitely for an infinite time, in an attempt to reach to the same height on the opposite hill!
