i hope you understood the method
kinetic energy is equal to charge×potential.
based on it u can derive the formula.

answer: 2:1
Explanation:
the de-broglie equation is=h÷mv......(1)
u=√2ev÷m......(2)
substituting (2)in(1)
=h÷m√2ev÷m
the two electrons are accelerated through 50volts and 200volts
√v1÷v=√200÷50=√4÷1
=2/1=2:1 option 4
