Document Summary
Summer 2018: two charges are separated by a distance d and exert mutual attractive forces of f on each other. If the charges are separated by a distance of d/2, what are the new mutual forces: f/4, f/2, 2f, 4f, none of these. F: four positive particles of equal charge. C, are located at the corners of a square of side 15. 0 cm. Calculate the magnitude of the force on the negative charge at the center of the square. C, placed: 83. 7 n/c, 7. 6 n/c, 3. 8 n/c, 0. 69 n/c, 0. 0: the electric field of two charges is shown below. What statement is correct: q1 > q2 > 0, q2 > q1 > 0, q1 > 0, q2 < 0, q1 < 0, q2 < 0, q1 < 0, q2 > 0. Electric field lines start at positive charge and end on negative charge.
