An electron is projected with an initial velocity v0 = 8.4 ×
M/s along the y-axis,which is the centerline between a pair of charged plates,as shown in the figure.The plates are 1.0 m long and are separated by 0.10 m.A uniform electric field of magnitude E in the +x-direction is present between the plates.If the magnitude of the acceleration of the electron is measured to be
What is the magnitude of the electric field between the plates? (e = 1.6 × 10-19 C,melectron = 9.11 × 10-31 kg)
A) 51,000 N/C
B) 45,000 N/C
C) 40,000 N/C
D) 35,000 N/C
E) 29,000 N/C
