Is momentum conserved when charge crosses a junction in an electric circuit? Why or why not?

Options

  1. AYes, because the uniform electric field keeps the drift velocity fixed.
  2. BNo, because there is an accumulation of charges on the surface of wires at the junction.
  3. CYes, because the electric field at the junction does not affect the direction of momentum.
  4. DNo, because the electric fields produced by the accumulation of charges can alter the direction of momentum.

Correct answer

D. No, because the electric fields produced by the accumulation of charges can alter the direction of momentum.

Step-by-step solution

Correct Option is : (D) No, because the electric fields produced by the accumulation of charges can alter the direction of momentum.
