1. Homework Statement In a laboratory, a particle of charge -6C is held stationary because it is placed in an electric field E=(0,0,-15)N/C which suspends it against gravity. What is the mass of the particle? Give answer in kg. 2. Homework Equations I THINK E= F/q F= ma or F= G m1 m2 /...

I don't really get what that means about it though.
