Question

Question 2 5 pts A B-gram particle with charge -0.7C, is shot out of a plate of positive charge. The plate generates an upward uniform electric field of 6 NIC. The particle has initial speed of 523 m/s, and is shot out at 67º. e Calculate the time the charge hits the plane again Question 3 5 pts In the previous problem, the computer generated quantities are now: • VO = 795 m/s . 0 = 340 • The others don't matter. You calculated a correct time of t=0.5 s. Now calculate how far horizontally the particle went, in meters.

please help solve question 2&3

Answer 1

Solution Initial speed you 523 mis u angle 0 - 670 Zo m = 8 & gm mo -0.008k 0.008kg force due to Electric field. fe qe F- -0.7 X 6 - 4.2 N would be therefore the direction of force downward, acceleration the ma = - 4.2 a = 4.2 =-525 mis 0.008 there fore time of flight t- & vosino a t- 2x523 x sin 67* 525 t= 9.8 sec total flight time. Question 2 Navo Yo=795 - 34° +-0.5 sec Range is given by formula R = Vocoso xt R: 795 cos 34° X 0.5 therefore R= 329.5 meters Answer.
