The $1.2\ kg$ sphere pictured below has a charge of $+1.0 \ C$.

If the electric field strength is $5.0\ V/m$ between the charged plates, how fast will the sphere be traveling because of the electric field by the time it reaches point $B$, if it starts from rest at point $A$?

A

$2.0 m/s$

B

$3.5 m/s$

C

$4.5 m/s$

D

$5.0 m/s$

E

$6.5 m/s$
