A potential barrier of

0.4\ \text{V}

exists across a p-n junction. An electron enters the junction from the n-side with a speed of

6.0\times10^5\ \text{m s}^{-1}

. The speed with which the electron enters the p-side will be

\dfrac x3\times10^5\ \text{m s}^{-1}

. The value of

x

is ______. (Given : mass of electron

=9\times10^{-31}\ \text{kg}

, charge on electron

=1.6\times10^{-19}\ \text{C}

)
