What is the proton's speed at point B? The mass of the proton is 1.67x10-27 kg and the charge of the proton is 1.60x10-19 C. 30 V 10 V -10 V 5. (8 pts) 40.0 pJ of energy is stored in a 1.50 cm 1.50 cm 1.50 cm region of uniform electric field. (p = 10-12). What is the electric field strength? You do not need to draw a diagram.

Working on a study guide for my physics class and i am kinda lost on this one, I know we need to use the wext formula. Please write everything out and show conversions.

Answer 1

Change in potential energy in an electric field does not depend on path followed by tge charge. It depends on final and initial potential.
