Answer:
m/s is answer for your questions
Answer:

Explanation:
The equation that relates electric field strength and force that a charge experiments by it is F=qE.
Newton's 2nd Law states F=ma, which for our case will mean:

We know from accelerated motion that 
In our case the proton is released from rest, so
and we get 
Substituting, we get our final velocity equation:

For the <em>proton </em>we know that
and
. Writing in S.I. d=0.0025m, we obtain:

D = RT
D is 8.4 cm or 84mm, R is 3.5mm (units of time, assuming seconds for now)
84 = 3.5T
T = 24 seconds
Answer:
weight. The force with which an object near the Earth or another celestial body is attracted toward the center of the body by gravity. An object's weight depends on its mass and the strength of the gravitational pull.
