Question
Particle X and Particie Y are located on the x axis. Particlex has a charge of s nc and is fixed at the origin; and Particle Y has a charge of -3nc, a mass of 7 mg, and is held at rest at x What is the magnitude of the electric field at the position of Particle Y? 7190000 N/c are correct. Your receipt no. is 147-9 46 What is the magnitude of the electric force on Particle Y? 0.0216 N Your are correct, Tries receipt no. is 147-1268 Previous what is the electric potential energy of Particle Y? -s.39x10"5 J Your are correct. Previous Tres receipt no. is 147-9114 You pull Particle Y to x 15.0 mm and hold it at rest there. What is the electric potential energy of Particle Y at its new position? submit Answer Incorrect. Tries 4/99 Previous Tries How much work did you do in moving Particle Y? Ans er Incorrect. Tries 1/99 Previous Tries You release Particle Y and it returns to its original position under the influence of the electric field alone. Particle Y's speed when it reaches its original position? What is submit Answer Tries 0W99 A circular loop of wire of radius 0.5 m and resistance 0.015 n lies in the plane of the page. A magnetic field directed out of the page increases in magnitude linearly with time from 0.0 T at t m 0 ms to 1.2 T at t What is the magnitude of the electromotive force that is induced in the loop? Submit Answer Tries 0W99 What is the magnitude of the electric current that is induced in the loop?Explanation / Answer
The only fourth part is solved as:
q1 = 5 nC
q2 = -3 nC
r = 15 mm
The potential energy = U = kq1q2/r = (9*10^9*5*10^-9*3*10^-9)/0.015 = 9*10^-6 J
