Two charged spheres, X and Y, are held a short distance apart. They do not touch.
Sphere X is positively charged. Sphere Y is negatively charged.
Which statement explains the force on sphere Y?
Y is in the electric field of X, and the field exerts a force on Y away from X
Electrons flow through the air from Y to X, and this pulls Y towards X
Y is in the magnetic field of X, and the field exerts a force on Y towards X
Y is in the electric field of X, and the field exerts a force on Y towards X
