Question

Two tiny beads are 25 cm apart with no other charges or fields present. Bead A carries 10 µC of charge and bead B carries 1 µC. Which one of the following statements is true about the magnitudes of the electric forces on these beads?

The force on A is 10 times the force on
b. The force on A is 100 times the force on
b. The force on A is exactly equal to the force on
b. The force on B is 100 times the force on
a. The force on B is 10 times the force on
a.

Answer 1

The correct answer is (B) The force on A is exactly equal to the force on B. Two tiny beads are 25 cm apart with no other charges or fields present. Bead A carries 10 µC of charge and bead B carries 1 µC. The statement that is true about the magnitudes of the electric forces on these beads is the force on A is exactly equal to B.
