a charge q is susupended between two horizontal plates connected to a battery.The polarity of the plates is now reversed.Find the acceleration of q

Dear student,

Due to existence of potential difference across the horizontal plates provided by the battery, there will be an electric field between the plates, due to which a charge placed in between them will experience a force.

The magnitude of the force due to battery of voltageconnected across plates with a separationbetween them is given as-


Hence the acceleration of the charge with massis

When the pority of the plates is reversed, only the direction of the acceleration is changed, and not the magnitude.
