Question

You managed to create charged tapes with unequal charges. Tape A carries a positive charge QA = +Q and tape B carries a negative charge that is five times as large, QB = -5Q. You measure the Coulomb forces of the tapes on each other and find
a.) The Coulomb force on A due to B is larger, but not five times as large, as the Coulomb force on B due to A.

b.) The Coulomb force on A due to B is the same as the Coulomb force on B due to A.

c.) The Coulomb force on A due to B is five times as large as the Coulomb force on B due to A.

d.) The Coulomb force on B due to A is five times as large as the Coulomb force on A due to B.

Explanation / Answer

Because F = KQ1Q2/r2

The force on one is also exerted on the other. Therefore, the answer is 3.
