3. At a particular instant, charge q₁ = 4.8 x 10^-6 C is at the point (0, 0.25 m, 0) and has velocity v₁ = (105 m/s). Charge q₂ = -10^-6 C is at the point (0.15 m, 0, 0) and has velocity v₂ = (105 m/s)î. At this instant, what are the magnitude and direction of the magnetic force that q₁ exerts on q₂?

Using convolution, determine and sketch the responses of a linear, time-invariant system with impulse response $h(t) = e^{-t/2}u(t)$ to each of the two inputs $x_1(t)$, $x_2(t)$ shown in Figures P4.5-1 and P4.5-2. Use $y_1(t)$ to denote the response to $x_1(t)$ and use $y_2(t)$ to denote the response to $x_2(t)$.

I think Mr. Very Important Policy Guru's statement raises some important points about increasing funding for Social Security and Medicare. However, there are a few errors and inconsistencies in the text that need to be corrected. Firstly, the abbreviation "FICA" should be expanded to "Federal Insurance Contributions Act" in the first sentence for clarity. Secondly, the phrase "approximately 7.7% of their compensation" should be followed by a comma for proper punctuation. Thirdly, in the sentence discussing the cap on payments, the phrase "let's ignore this" should be enclosed in parentheses for clarity. Fourthly, in the sentence discussing the purpose of the question, the phrase "or no one earns more than $137,000" should be enclosed in parentheses for clarity. Fifthly, in the sentence discussing the use of FICA taxes, the phrase "may not have adequate funding" should be corrected to "may not have sufficient funding" for proper grammar. Lastly, in Mr. Very Important Policy Guru's statement, the phrase "increase employers' payments" should be corrected to "increase employers' payment" for consistency with the singular noun "payment" used earlier in the sentence. Overall, the text should be formatted and presented in a clear and coherent manner, with the corrections made to the errors mentioned above.

I demonstrated a small motor that was powered by a battery today in class. The circuit can be considered as below. The square loop is free to rotate along an axis that is perpendicular to $\vec{B}$ (dashed line). Ignore the inhomogeneity of the magnetic field (assume a constant $\vec{B}$). Explain why we saw the square loop rotating. (Note: you need to go through an entire $2\pi$ rotation. If your results do not make sense, what tricks might I have played in there?)
