An accelerating voltage of 2500 V is applied to an electron gun, producing a beam of electrons originally traveling horizontally in a vacuum toward the center of a viewing screen 35.0 cm away. What is the deflection of the screen caused by the earth's gravitational field?

I'm not sure where to begin on this. Please help!

The accelerating voltage that is applied to an electron gun is 64kV, and the horizontal distance from the gun to a viewing screen is0.54 m.
The charge on an electron is 1.60218 × 10^-19 C and its mass is9.10939 × 10^-31 kg.
What is the deflection caused by the vertical component of theEarth’s magnetic field or strength 4 × 10^-5 T, assuming that anychange in the horizontal component of the beam velocity isnegligible.
Answer in units of m.

Thank you!

In the cathode-ray tube a beam of electrons is injectedhorizontally into the exact parallel plate region.Each plate haslength,L =1.5cm separation, d= 0.2cm and each plate carries auniform charge density of magnitude σ=2.5x10-7C/m2. What minimum initial speed v must the electronshave to ensure that they do not strike the upper plate



b) Knowing that the electron travels in a straight line afterexiting the electric field region and if th screen is D=12cm fromthe end of the plates, what will be the total deflection of theelectrons when they hit the screen?



I have done the first part with ease but with (b). I dont knowhow to calculate the total deflection of the electrons when theyhit the screen
