1. The problem statement, all variables and given/known data A small object of mass 3.64 g and charge -18.1 µC is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. What are the magnitude and direction of the electric field? 2. Relevant equations E=F/q 3. The attempt at a solution I solved for the magnitude and was fine with that but was wondering why the electric field direction would be downwards? Why couldn't it be upwards? E = m*g / -q = -# My logic was that a - electric field upwards would make the charged object hover since - and - repel. I guess if it was going downwards the same effect would still occur, but I don't understand (if this is even right...) how to determine if up or down. Am i completely off track on how to think about this?
