Alright yeah, so I think I can do
F=k(e^2)/r^2 which is the force of the capacitator on q1
which would then = to the same force of q2 exerted on q1
so Fq2 = Fcap but how do I find Fq2 now? I don't know the formula for electrons.
Can I just assume that q2 = -q1? and skip the Fq2...
Homework Statement
Two charges are placed between the plates of a parallel plate capacitor.
One charge is q1 and the other is q2 = 5.00 microC. The charge per unit
area on each of the plates has a magnitude of σ = 1.30 x 10^-4 C/m^2. The
magnitude of the force on q1 due to q2 equals...
Wait.. am I supposed to double the charge for the electron since it's a 2e- substance? The hydrogen example given in the book didn't have the 2 in it and just went k(e^2)/r^2
Alright.. I still don't get it though, how do I know what the mass is for the e-?
And also I don't know how to draw an fbd for this.. Theres 2 protons, (I assume not at the center), so where do I draw them?
Sorry it's been awhile I've done a fbd... well tbh I've never done one for an electron...
Homework Statement Multiple-Concept Example 3 provides some pertinent background for this problem. Suppose a single electron orbits about a nucleus containing two protons (2e), as would be the case for a helium atom from which one of the two naturally occurring electrons is removed. The radius...
Yeah I've confirmed it with someone else. The equation I used is correct. Either the spring constant is too small or/and the natural length is too small. The maximum the spring can absorb is even less than 1 J which leaves more than 19J left for the 2 masses KE to fill and can't be filled with...
An object with mass m1=0.4kg moves at v0=10 m/s toward a second object with mass m2 = 0.8kg. Attached to the second object is a spring with spring constant k = 200N/m, and natural length L0 = 0.1m. As the objects collide the spring is initially compressed. After compressing a maximum amount the...
Alright so yeah. After doing a couple other trials, I'll basically get numbers larger than the L0 (natural length) for dX. Which can't be true because it can only compress so much. It cannot be more than 0.1m.
Homework Statement
Mass 1 at 10m/s collides into mass 2 at rest, which has a spring attached to it. The second mass has a spring at 200N/m and natural length L0 = 0.1m. At the instant they collide, the spring is compressed to its max amount and the masses move with the same speed V. Determine...
Homework Statement
A disk begins spinning from rest with angular acceleration @ = 12 rad/s^2. A small object is on the disk a distance r = 2.0 cm from the center. What is the magnitude of the net acceleration of the object after a time t = 0.25s?
(alpha) @ = 12 rad/s^2
r = 2 cm
t = 0.25 s...
Homework Statement
A ball with mass 1.0 kg and radius 0.20m rolls without slipping along level ground with a speed of 10 m/s. The ball then rolls up an incline reaching a maximum vertical height of 8.0 m. What is the moment of inertia of the ball? (Do not assume the ball is a uniform sphere)...
