Question 14 (1 point) For a system that contains a rock falling through the air, which situation is always true?

The total mechanical energy of the system is conserved.

The total energy of the system is conserved.

The total potential energy of the system is conserved.

The total kinetic energy of the system is conserved.

the one with the highest speed

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
