Question
A parallel plate capacitor has smooth square plates of side “a”. It is charged by a battery so that, the charge density becomes s . After charging, the battery is disconnected. Now a smooth dielectric slab of length a which can fill the space between the plates is introduced between the plates from one side between the plates
- The slab can execute SHM between the plates
- The plate can execute oscillatory motion which is not SHM
- The magnitude of the force experienced by the slab is constant
- The magnitude of the force experienced by the slab is not constant
The correct answer is: The plate can execute oscillatory motion which is not SHM
