If an electron enters into a space between the plates of a parallel plate capacitor at an angle $α$ with the plates and leaves at an angle $β$ to the plates. The ratio of its kinetic energy while entering the capacitor to that while leaving will be

Options:

Answer:

Solution:

In the direction parallel to plate

$v_{1} \cos α = v_{2} \cos β$

$\frac{v_{1}}{v_{2}} = \frac{\cos β}{\cos α}$

ratio of kinetic energy

$\frac{{KE}_{1}}{{KE}_{2}} = {(\frac{v_{1}}{v_{2}})}^{2}$

$\frac{{KE}_{1}}{{KE}_{2}} = {(\frac{\cos β}{\cos α})}^{2}$
