1) An object with a net charge of 19 µC is placed
in a uniform electric field of 629 N/C, directed
vertically.

What is the mass of this object if it floats
in this electric field? The acceleration due to
gravity is 9.81 m/s 2
Answer in units of kg

2) An object having a net charge of 20 µC is
placed in a uniform electric field of 934 N/C
directed vertically up.

What is the mass of this object if it “floats”
in the field? The acceleration due to gravity
