If weight is the force of gravity on an object, then your weight can change if the force of gravity is different on a different planet?

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

Two 2.0-cm-diameter disks face each other, 1.0 mm apart. they are charged to ±10 nc. what is the electric field strength between the disks? a proton is shot from the negative disk toward the positive disk. what launch speed must the proton have to just barely reach the positive disk?

The ability to make things happen is also called a. heat b. force c. matter d. energy
