If an electron enters a space between the plates of a parallel plate capacitor at an angle `theta_(1)` with the plates and leaves at an angle `theta_(2)` to the plates, the ratio of its kinetic energy while entering the capacitor to that while leaving will be

A

`(cos^(2)theta_(2))/(cos^(2)theta_(1))`

B

`(cos^(2)theta_(1))/(cos^(2)theta_(2))`

C
