I would definitely think its B....
Explanation:
When neutral objects are placed in the vicinity of charged objects,they get attracted.
The isolated neutral object has positive charge and negative charge spread throughout it completely.
When a charged particle is brought,the opposite charges in the neutral object occupy the positions near to the charged particle and the like charges occupy the positions far from the charged particle.
This creates a dipole with some dipole moment.
This dipole attracts to the field of the charged particle.
Think of a car, when we have to add oil. If we didn't then the friction would cause so much heat that the engine would break and fall apart.
Answer: 204.29 *10^-6 J
Explanation: In order to explain this question we have to consider to following expression for the potencial and electric field in a capacitor, which is given by;
E*d=V where d is the separation between plates and E and V are the electric field and the voltage difference in the plates.
For the maximun electric field, V max es equal
Vmax=Emax*d= 222*10^3 *1.96*10^-3=435.12 V
We also know that potential energy stores by a capacitor with a constant dielectric κ is given by:
E=0.5*C*V^2, where C is the capacity and V the voltage.
For two plates capacitor C is equalk to:
C= k*ε*A/d where A and d are the area and the separation in the capacitor. εo is a constant equal 8.85*10^-12 F/m
Then;
E=[(0.5*5.85*8.85*10^-12*0.0817)/(1.96*10^-3)]*(435.12)^2= 204.29 *10^-6 J
