Academics

Problem: A small ball has a mass of mass m 4.0 x 10-8 kg and a charge of q = +2.0 x 10^-5 C. It enters a box with an initial speed of v0 = 1.0 x 10⁴ m/s. The point where the charge leaves the box is at a voltage 350 kV higher than the entry point.

Part A: What is the final speed (in m/s) of the ball as it exits the box?
