Question

(13%) Problem 3: An electron has an initial velocity of 4.95 × 106 ms in a uniform 1.9 × 105 N/C electric field. The field accelerates the electron in the direction opposite to its initial velocity. p Δ 25% Part (a) What is the direction of the electric field? Grade Summa Deductions Potential The field is in the direction to the right of the electron's initial veloci 096 100% The field is in the direction of the electron's initial velocitv The field is in another direction not listed here Submissions O The field is in the opposite direction of the electron's initial velocity Attempts remaining: 3 (33% per attempt) detailed view Submit Hint I give up!
