In the figure particles 1 and 2 of charge q1 = q2 = +3.20 x 10-19 Care on a y axis at distance d = 18.2 cm from the origin. Particle 3 of charge q3 = +43.20 x 10-19 C is moved gradually along the x axis from x = 0 to x = +5.17 m. At what values of x will the magnitude of the electrostatic force on the third particle from the other two particles be (a) minimum and (b) maximum? What are the (c) minimum and (d) maximum magnitudes of the force?In the figure four particles form a square with edge length a = 4.64 x 10-2 m. The charges are q1 = q4 = 2.72 x 10-15 C and q2 = q3 = q. (a) What is q if the net electrostatic force on particle 1 is zero? (b) Is there any value of q that makes the net electrostatic force on each of the four particles zero? 12 3 4The figure shows four identical conducting spheres that are actually well separated from one another. Sphere W(with an initial charge of zero) is touched to sphere A and then they are separated. Next, sphere Wis touched to sphere B (with an initial charge of -30e) and then they are separated. Finally, sphere Wis touched to sphere C (with an initial charge of 50e), and then they are separated. The final charge on sphere Wis 20e. What multiple of e gives the initial charge on sphere A? A B WFind A and identify X in the following nuclear reactions: (a)1H + 'Be - AX + n; (b)12C + 1H - AX; (c)15N + 1H - 4He + Ax. (a) A = i X: (b) A = i X: (c) A = i X: v
