Solve the following problem given below:
Problem: A beam of charged particles with density 35000000000000 particles/m3 is directed due east. Each particle carries a charge of +3e, and moves at a speed of 2.98×105 m/s.
Part A: What are the magnitude and direction of the average current density J of this beam?
Part B: You do not have enough information to calculate the current flowing in the beam. What additional information do you need?
I need expert help to solve the above question.
