Accepted Answer

Q6 a Answer C The potential difference decreases Inserting the dielectric material between the plates increases the capacitance of capacitor by dimensionless factor k dielectric constant C C 0 k By definition of capacitance C 0 QdV o as inserting the dielectric the capacitance increases the potential difference must decreases which leads to increase in capacitance Also the potential difference decreases by same factor k dv dv 0 k b Answer C Stored energy decreases By definition U 0 Q 2 2C 0 as Q remains unchanged and C 0 increases by factor k so the energy decreases by factor k U Q 2 2C Q 2 2C 0 k U 0 k c Answer B The object is affected by a force that pulls the objects towards the area between the plates In part b we have seen that energy decrease which leads to negative work done on dielectric This means the force must pulls the object towards the area between the plate ....
