An electron is projected with an initial velocity

v _ { 0 } = 8.4 \times 10 ^ { 7 } \mathrm {~m} / \mathrm { 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 \mathrm {~m}

long and are separated by

0.10 \mathrm {~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?

\left( e = 1.6 \times 10 ^ { - 19 } \mathrm { C } \right.

m _ { \text {electron } } = 9.11 \times 10 - 31 \mathrm {~kg}

)
