I NEED THESE TWO ANSWERS BEFORE MIDNIGHT PST. I WILL RATELIFESAVER FOR CORRECT ANSWERS!
In a cathode-ray tube (CRT), an electron travels in a vacuumand enters a region between two "deflection" plates which haveequal and opposite charges. The dimensions of each plate are L = 11cm by d = 4 cm, and the gap between them is h = 2.5 mm. (Note: thediagram is not drawn to scale and the direction of the electricfield may not be correct, depending on yourrandomization.)
During a 0.001s interval while it is between the plates, the changeof the momentum of the electron ?p is < 0, -8.80e-17, 0 > kgm/s.
(a) What is the electric field between the plates? Hint: remember the Momentum Principle (the relationship betweenImpulse and change in momentum.)
=________ N/C
(b) What is the charge (both magnitude and sign) of the upperplate?
