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?
1.
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 q,.
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 x 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 x 0-6C).

5. 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 (2x 10-8sec.), determine: 1) The electric field intensity. 2) The electron velocity when it reaches the
positive bar.
