Two parallel plates have opposite charges and a distance between them measured to be 1.00 mm. The potential between the plates is 30.0V. A proton is launched with an initial horizontal velocity of 1.50e3 m/s at a height of 0.500mm above the bottom plate. Assume the gravity is negligible.
A)) how long does it take for the proton to strike the top plate (hint: this is a projectile motion problem, find acceleration).
B)) What is the horizontal range that the proton travels??
