Question

Questions . What is the electric field between parallel plates that are separated by 1 cm when the voltage between the plates is SkV t is the electric charge of each plate wher the voltage between the plates is 5 kV? 3. How will the force of interaction change if between the charged parallel plates is inserted a sheet of dielectric? 4. The electric fux through a closed surtficeis found to be 25N.m, What quantity of charge is enclosed by the surfacet 5. A closed surface encloses a net charge of 5.5x 106 C. What is the net electric flux through the surface? Nehr uniy o hag s eodbyte

Explanation / Answer

1. E = V / d = (5 x 10^3 Volt) / (0.01 m)

E = 5 x 10^5 V/m

2. C = e0 A / d = (8.854 x 10^-12)(0.15^2)/(0.01)

C = 2 x 10^-11 F  

Q = C V = 99.6 x 10^-9 C

3. field between the plates decreases.

4. net flux = Q / e0

2.5 = Q / (8.854 x10^-12)

Q = 22.1 x 10^-12 C

5. flux = (5.5 x 10^-6) / (8.854 x 10^-12)

= 6.21 x 10^5 N m^2 / C
