What is the de Broglie wavelength of an electron with momentum $10^{-24} kg \cdot m/s$? (Planck's constant $h = 6.626 imes 10^{-34} J \cdot s$)

An electron with initial de-Broglie wavelength $\lambda_0$ is moving with velocity $V_0 \hat{i}$ and enters a region with electric field $-E_0 \hat{i}$. How much time will it take for its de-Broglie wavelength to become $2\lambda_0$?
