Three charges are located at the corners of an equilateral triangle, as depicted in Fig. 15.26. What are the magnitude and the direction of the force on q1?
Answer to relevant QuestionsFour charges are located at the corners of a square, as illustrated in Fig. 15.27. What are the magnitude and the direction of the force (a) On charge q2 and (b) On charge q4? An electron is acted on by two electric forces, one of 2.7 x 10-14 N acting upward and a second of 3.8 x 10-14 N acting to the right. What is the magnitude of the electric field at the electron’s location? An alpha particle is the nucleus of a helium atom with no electrons. (a) What would be the charge on two alpha particles? (b) How many electrons would you need to add to make an alpha particle into a helium atom? Compute the electric field at a point 4.0 cm from q2 along a line running toward q3 in Fig. 15.27. Suppose a Gaussian surface encloses both a positive point charge that has six field lines leaving it and a negative point charge with twice the magnitude of charge of the positive one. What is the net number of field lines ...
