A 100V battery is connected to two oppositely charged plates that are 10cm apart. i. what is the magnitude of the electric field?

ii. Calculate the electric force exerted on a +200uC point charge.

iii. What is the electric potential energy of the charge when its 8cm and 2cm from the negativity charged plate?

iv. How much work was required to to move the charge from 8cm to 2cm?

v. If the 10 g point charge was at rest at point A, What is the final speed at point B?
