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.
