Problem: A proton's speed as it passes point A is 50000 m/s . It follows the trajectory shown in the figure.(Figure 1)What is the proton's speed at point B?

FREE Expert Solution

We'll use the law of conservation of energy:

P.Ei+K.Ei=P.Ef+K.Ef

The work done by a proton is given by:

W=qV=(1.602×10-19)[30-(-10)]

W = 6.408 × 10-18 J
