An Electron Is Projected with an Initial Velocity V₀ = $10 ^ { 7 }$

question 48

Multiple Choice

An electron is projected with an initial velocity v₀ = 8.4 × $10 ^ { 7 }$ 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 $8.9 \times 10 ^ { 15 } \mathrm {~m} / \mathrm { s } ^ { 2 }$ what is the magnitude of the electric field between the plates? (e = 1.6 × 10^-19 C, m_electron = 9.11 × 10^-31 kg)
