Compute all parts of given problem:
Problem: A small piece of dust of mass m = 1.6 mu or micro g (micrograms) travels through an electric air cleaner in which the electric field is 557 N/C. The electric force on the dust particle is equal to the weight of the particle.
Part A: What is the Charge on the dust particle?
Part B: If this charge is provided by an excess of electrons, how many electrons does that correspond to?
Please provide me complete solution for the above problem so I can get right solution.
