Portage Phys 165 Module 7 Exam
A 26.0-nF capacitor is hooked up to a 36.0-v battery. The plate separation is 35.Four µm and
there is a vacuum in among the plates.
Eo=eight.85x10^-12C^2/Nm^2
a. What is the vicinity of one of the plates?
B. How plenty fee is saved on one of the plates?
C. How much electricity is stored in the capacitor? - ANS-a) C=Eo*A/d revised as A=d*C/Eo
Answer in m^2
b) Q=CV (2.60x10^-8F)(12.0V) Answer in MewC (?)
c) Uc=C(deltaV)^2/2
Answer in Mew J
A fifty six.Zero nF capacitor is attached to a 7.50 v battery. The plate separation is 25.4 µm and
there is a vacuum in between the plates.
Eo = 8.85x10^-12 C^2/Nm^2
a. What is the region of one of the plates?
B. How a great deal price is stored on one of the plates?
C. How a great deal electricity is saved in the capacitor? - ANS-a) C=Eo*A/d Revised as
A=dC/Eo Answer in m^2
b) Q=CV Answer in mewC
c) Uc= C*deltaV^2/2 Answer in mewJ
A negatively charged rod touches a neutral electroscope, giving the electroscope a internet rate.
A. What is the name of this manner of charging an object?
B. What is the sign of the internet fee of the electroscope after the rod touches it? - ANS-a)
Charging by way of conduction
b) Negative
A proton is in an electric powered area with a importance of three.79 x 106 N/C directed to the
West.
A. What is the value of the electric force appearing at the proton?
B. In what route is the pressure acting at the proton?
C. If that is the handiest pressure appearing at the proton and the mass of the proton is 1.Sixty
seven x 10-27 kg, what is the acceleration of the proton?
D. If the proton is replaced with an electron, how will the significance and course of the pressure
appearing on the electron examine to the force exerted on the proton? - ANS-a) E=F/q Revised
as F=EQ Answer in Newtons
B) West
C) Use F=ma Revised as a=F/m Answer in m/s^2
D) It is the equal value, directed East
