Answer:
a) r=4.24cm d=1 cm
b)
Explanation:
The capacitance depends only of the geometry of the capacitor so to design in this case knowing the Voltage and the electric field
The distance must be the separation the r distance can be find also using
But now don't know the charge these plates can hold yet so
a).
d=0.01m
b).
(a) The mass of the bullet is 
and its speed is 
, so its momentum is
The pitcher claims that he can throw the ball with the same momentum p of the ball. Since the mass of the ball is m=0.148 kg, this means that the velocity of the ball must be:
(b) The kinetic energy of the bullet is:
while the kinetic energy of the ball is:
So, the bullet has greater kinetic energy than the ball.
