Motion of charge particle in electric field

Open program https://ophysics.com/em6.html

Set the following values

Voltage  = 40 V

Distance between plates  = 5 cm

Initial velocity = 8 x 10⁵ m/s

Charge on particle = 0.3 μC

Mass of particle = 0.3 x 10^-16 kg

Particle enter in the field at a vertical distance on 2.5 cm

• Calculate how much time the particle will strike the plate (lower or upper?)

4.2 Horizontal distance travelled in this time.

4.3 Run the program and check your results obtained in calculations. Include the screen shot in the lab report.

4.4 What will happen if the polarity of charge will be opposite. Predict the result and run the simulation. Are the results same as you predicted? Include the screen shot in the lab report.
