Given the following, what is the net force on the particle? What is the acceleration of the particle? How long will it take to strike one of the plates?

A particle with a charge of #-4.00 x 10^-6 C# moves through a uniform electric field of #70.0 N/C# directed downwards. It is moving horizontally at #12.0 cm/s# exactly between two plates that are #10.0 cm# apart. The particle has a mass of #0.0400 g#.

Answer 1

I tried this...although I think the horizontal velocity is not right (but shouldn't be a problem because I didn't use it anyway)...let me know what do you think of it.

The net force on the particle is the total of all the individual forces acting on it; its acceleration is found by dividing the net force by the particle's mass; and the time it takes for the particle to strike a plate is calculated using equations of motion.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
