Using the symmetry of the arrangement, determine the direction of the force on q in the figure below, given that qa=qb=+7.50C and qc = qd = 7.50C. (b) Calculate the magnitude of the force on the charge q, given that the square is 10.0 cm on a side and q = 2.00 C.
A sphere has a net charge of 8.05 nC, and a negatively charged rod has a charge of 6.03 nC. The sphere and rod undergo a process such that 5.00 109 electrons are transferred from the rod to the sphere. What are the charges of the sphere and the rod after this process?
Object A has a charge of +2 C, and object B has a charge of +6 C. Which statement is true? (a) FAB = 3FBA (b) FAB = FBA (c) 3FAB = FBA
What is the repulsive force between two pith balls that are 8.00 cm apart and have equal charges of 30.0 nC?
Three charged particles are located at the corners of an equilateral triangle as shown in Figure P19.9. Calculate the total electric force on the 7.00-C charge.
Suppose a woman carries an excess charge. To maintain her charged status can she he standing on just any pair of shoes? How would you discharge her? What are the consequences if she simply walks away?
