Question

FFFFTFT Is not correct! Please help More True Or False Consider two oppositely charged, isolated parallel plates separated by distance D, with capacitance C, charge Q, and stored energy U. D is small compared to the dimensions of the plates. For each statement below, select "True" or "False". Inserting a dielectric decreases C. Increasing D, increases the E field. When D is halved, Q stays the same. Inserting a dielectric decreases U. Inserting a dielectric increases Q. When D is doubled, U is unchanged. When D is doubled, C is halved.

Explanation / Answer

a) Inserting dielectric , increases capacitance = K ( original capacitance) : False

b)False , E = charge density / permivity ( it's independent of distance)'

c) false

d)True ( inserting a dielectric will decease the energy stored)

e)false ,  charges remain same

f)false, energy reduces by a factor of 2

g)true
