Q. In a cathode-ray tube, a beam of electrons is projected horizontally with a speed of 1.0x10^9 cm/s into a region between a pair of horizontal plates 2.00 cm long. An electric field between the plates causes the constant downward acceleration of the electrons of magnitude 1.0x1017 cm/s2. Find (a) time required for the electrons to pass through the plates, (b) vertical displacement of the beam in passing through the plates, and (c) components of the velocity of the beam is it emerges from the plates.
A stone with a mass of 0.700 is attached to one end of a string 0.8 long. The string will break if its tension exceeds 65.0 . The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string remains fixed.
What is the magnitude of the electric field. A 50-gram super ball traveling at 25m/s is bounced off a brick wall and rebounds at 22 m/s. A high speed camera records this event. If the ball is in contact with wall for 3.5 ms, what is the average acc..
