What is the electric charge of each plate whe the voltage between the plates is 5 kV? 3. How will the f 4· The electric flux through a closed surface is found to be 2.5-..w 5. A closed surface encloses a net charge of 5.5x106 C. What is the net electric flux through the surface? orce of interaction change if between the charged parallel plates is inserted a sheet of dielectric? N.m*, What quantity of charge is enclosed by the surface

Explanation / Answer

1) V = 5 kV, d = 1 cm

Electric field = E = V/d = 5000/0.01 = 5*10^5 N/C

2) V = 5 kV, d = 1 cm

Electric field = E = V/d = 5000/0.01 = 5*10^5 N/C

4) Flux = F = 2.5 Nm^2/C

Now F = Q/eo ==========> Q = F*e0 = 2.5*8.85*10^-12 = 22.1 pC

5) Q = 5.5*10^-6 C

Flux = Q/eo = 5.5*10^-6/(8.85*10^-12) = 6.2*10^5 Nm^2/C
