Consider the circuit in the figure.
Find the current in the 1.3 Ω resistor. Answer in units of A.
Find the potential difference across the 1.3 Ω resistor. Answer in units of V.
Find the current in the 10.0 Ω resistor. Answer in units of A.
V = IR
OK, nevermind. I did what I just posted and I got it right!
F1 = ((8.9875e-9)(2e-9)(3e-9))/((sqroot(8))2) = 6.740625e-9
F2 = ((8.9875e-9)(2e-9)(6e-9))/((sqroot(8))2) = 1.348125e-8
sqroot ((F1)^2 + (F2)^2) = approx. 1.51e-8
ok, then what about the "2*nC" part? nC is nano-Coulombs though...
Am I supposed to find the force between 3nC and 2nC and then the force between 2nC and 6nC? After that, do I use the Pythagorean theorem to get the resultant force?
Three positive point charges are arranged in a triangular pattern in a plane, as shown below. The Coulomb constant is 8.98755 × 109 N · m2/C2.
Find the magnitude of the net electric force on the 2 nC charge. Answer in units of N.
Fe = (kq1q2) / (d2)...
A particle with charge −9 μC is located on the x-axis at the point 8 cm, and a second particle with charge 5 μC is placed on the x-axis at 6 cm. The Coulomb constant is 8.9875 × 109 N · m2/C2. What is the magnitude of the total electrostatic force on a third particle with...
The length of a string is 1440 cm. The
string is held fixed at each end. The string
vibrates in eight sections; i.e., the string has
eight antinodes, and the string vibrates at
What is the fundamental frequency? Answer
in units of Hz.
f = nv /...
Yes, I did convert it into kg when I did the problem again but the site still said I was wrong :(
my answers thus far:
3574.35 (w/o changing to kg)
1.833 (no idea)
35.7435 (change to kg)
0.01 (from a bad source :( )
