Find the relation between the potential difference and the wavelength of an electron which starts its motion from rest

-> Lec2-Assig... Electronic Physics Lecture 2 - Assignments Lecture 2 - Assignments 1. What must be the distance between point charge q, = 26.0 µC and point charge q2 = -47.0 µC for the electrostatic force between them to have a magnitude of 5.70 N? 2. Charge q, is +1.00 µC . Located 0.500 m to the right of q, is charge q2 (+12.00µC). At a distance of 1.50 m in the +y-direction from charge q, is charge q3 (23.00µC). Find the magnitude and direction of the net electrical force on charge q1. 3. Find a relation between the potential difference and the wavelength of an electron which starts its motion from rest. In the following figure, two charges: (q, = 2 × 10-6C) and (q2 = 2.5 x 10-6C), find the magnitude and the direction of the resultant force exerted by the two charges on a third one (Q = 5 × 0-6C). 4. 0.5m 0.3m .0.4m.. 0.3m 0.5m A uniform electric field between two parallel bars (25 cm apart), an electron moves from rest from the negative bar and reaches the other bar (the positive bar) in (2× 10-8sec.), determine: 1) The electric field intensity. 2) The electron velocity when it reaches the positive bar. 5.
