Electrostatics Question 52
Question: A frictionless dielectric plate $ S $ is kept on a frictionless table $ T $ . A charged parallel plate capacitance $ C $ (of which the plates are frictionless) is kept near it. The plate $ S $ is between the plates. When the plate $ S $ is left between the plates [CPMT 1988]
Options:
A) It will remain stationary on the table
B) It is pulled by the capacitor and will pass on the other end
C) It is pulled between the plates and will remain there
D) All the above statements are false
