2. Two 57 ohm resistors are connected in series to a 12 volt battery. (MUST SHOW YOUR WORK)
a. What is the total resistance of the circuit?
b. What is the current through the circuit?
3. A proton is traveling 2E6 m/s when a force causes an acceleration of 1E15 m/s^2.n (MUST SHOW YOUR WORK)
a. If the force is electric, what is the electric field?
b. If the force is magnetic, what is the magnetic field?
c. The charge of a proton is 1.6E-19 C and its mass is 1.67E-27 kg
4. (MUST SHOW YOUR WORK) What is the electric field 0.5 m from a 1 Coulomb charge?1
What would the force be on a 3*10^-6 Coulomb charge placed at that position? 2
k = 9E9 N m^2/C^2
Explanation / Answer
1. What is Newton's 2nd Law of motion?
F = ma
a = v^2/r
y = 1/2 a t^2
p = mv
KE = 1/2 m v^2
2
(a)total resistance=2x57=114 ohm (because they are in series )
(b)
V=IR
I=V/R=12/114=0.105 Amp
