Two Tiny Metal Spheres Are Fixed to the Ends of a Non-Conducting

question 4

Multiple Choice

Two tiny metal spheres are fixed to the ends of a non-conducting string of length .Equal charges, +q, are placed on the metal spheres.Randall says that the force on the string has magnitude .Tilden says that the tension in the string has magnitude .Which one, if either, is correct?

• A)Randall, because both charges exert forces on the string, but the tension is
• B)Tilden, because both charges exert forces on the string, but the net force is
• C)Both are correct, because both charges exert forces on the string.
• D)Neither is correct, because both the tension and the force have magnitude
• E)Neither is correct, because the tension is , but the net force is 0.
