Answer for 17 is D.
Uniform electric field implies constant force.
Alpha particle ~4amu
Proton ~1amu
Since f = m*a, and is constant, alpha particle mass is 4* proton, therefore it's acceleration is 1/4 of proton.
Nep.

Charge of alpha particle is twice charge on proton, so acceleration ends up as 1/2

F = ma
F = qE
qE = ma

a = qE/m
