An object with a net charge of 20 µC is placed in a uniform electric field of 627 N/C, directed vertically. What is the mass of the object if it floats in the electric field?
627 N/C * 20*10^-6 C – mg = 0
since the forces sum to zero because it is floating
the main thing here is converting µC to C and notice the “C” simplifies and everything is in the same dimension – Newtons
