Two horizontal metal plates, each 10.0 cm square, are aligned 1.00 cm apart with one above the other. They are given equal-magnitude charges of opposite sign so that a uniform downward electric field of 2.02*10^3 N/C exists in the region between them. A particle of mass 2.00*10^16kg and with a positive charge of 1.03*10^6 C leaves the center of the bottom negative plate with an initial speed of 1.02*10^5 m/s at an angle of 37.0° above the horizontal.
(a) Describe the trajectory of the particle.
a parabolaa circle a helixa straight lineYour answer is correct.
(b) Which plate does it strike?
negative platepositive plate It does not strike either plate. Your answer is correct.
(c) Where does it strike, relative to its starting point? (Enter the horizontal distance from the initial position.)
= m.
