First we calculate the Electric Force
F = qE = 1.6E-19 * 4 E+4 = 6.4 E -15 N
This Force is equal to mass*acceleration
F = m*a
Mass of the electron = 9.1 E-31 Kg
Mass of the proton = 1.67 E -27 Kg
Acceleration of electron = 6.4 E -15 / 9.1 E -31 = 7.033 E 15 [m/s**2]
Acceleration of proton = 6.4 E -15 / 1.67 E -27 = 3.832 E 12 [m/s**2]
Linear momentum is conserved, so the speed of the block after
the bullet has passed through it and continued on its way is
(383 · mass of the bullet) divided by (mass of the block)
Answer:

gravity
The type of stars in the areas give different colors to the galactic disk. The galactic disk appears blue because it has a large proportion of young, hot, main-sequence stars. The galactic bulge appears red because it contains many red giants and supergiants. The reddish hue of the galactic bulge indicates that new stars aren't being formed there.
