Question

The magnitude of the electric force on a point charge placed inside a parallel plate capacitor 67 Newtons. If the charge is moved 5 times closer to the positive sheet (but still inside the capacitor), what is the magnitude of the electric force on the point charge now in Newtons?

Answer 1

here,

the magnitude of electric feild is constant through the capcitor

and the electric force , F = q * E

as q and E , both remains the same

so,

the magnitude of the electric force on the point charge now is also 67 N
