Suppose there is now friction and the equation of motion becomes x+2yx+w²x = 0, where 0 is some constant of friction. γ i. Find the general solution for x(t), under the assumption that w. You do not need to impose initial conditions here. ii. What is the range of for which the above solution is (1) heavily damped; (2) lightly damped. What happens to the above solution and the physical system when y = w?

2. Consider three charges in the figure below. Assume that distances between charges d1-d3=4.24 m, d2-6 m and ẞ1=ẞ2 and ẞ3-90°. Here d₁ is the distance between Q1 and Q3, d2 is distance between Q1 and Q2, and d3 is a distance between Q2 and Q3. The charges are Q1=7 C, Q2-6 C and Q3=7 C. Calculate the magnitude of electric field E at the points a) P₁ (x = 0, y = 2.12), b) P2 (x 2.12, y = 2.12). Q₁ d₂ d₁ B₁ P₁ P2 B3 B₂ Q2 X Q₂ d3
