What is the de Broglie wavelength of an electron that has been accelerated through a potential difference of 1 MV ( you must use the relativistic mass and energy expressions at this high energy.)

ans. 8.7 x 10^-13

2. Relevant equations

M= Mo/ square root (1 - v^2/c^2)

3. The attempt at a solution

I have no idea where to go with this question i am completely stumped, can someone please steer me in some direction to understanding such and getting the right answer, thank you and i really appreciate it.
