7. [-/10 Points] DETAILS MY NOTES ASK YOUR TEACHER A uniform electric field of magnitude 439 NUC pointing in the positive-rection acts on an electron, which is initially at rest. The electron has moved 2.50 cm (a) What is the work done by the field on the electron? (b) What is the change in potencial energy associated with the electron SERCP11 16.1.P.001. (c) What is the velocity of the electron? m/s magnstude direction Need Help? PAHT Sooo 8. [-/5 Points] DETAILS SERCP11 16.2.OP.012. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The figure below shows two charged particles separated by a distance of d-3.50 cm. The charges are d, -20.0 nC and 43-26.5 nC. Point is at the midpoint between the twil charges, and point A is at the peak of an equilateral triangle, with each side of length d, as shown (Assume the zero of electric potential is at infinity) (a) What is the electric potential (in kV) at point A? kv PRACTICE ANOTHER (b) What is the electric potential (in kv) at point 87
