Charge of 1 electron = 1.6*10^-19 C
Net Charge Q, = 1 C
No of Electrons, = 1/(1.6*10^-19)
N = 6.3 * 10^18
2)
Electrical Field, E = k*q/r^2
E = 8.9*10^9 * q^2)/
Force = m*a
Electrical Force = k*q^2/r^2
k*q^2/r^2 = m*a
(8.9*10^9*q^2)/(6.4/100)^2 = 3.2*10^-3 * 538
q = 8.9*10^-7
q = 890

Question 29 1 pts Two charged particles repel each other with a force F. If the charge of one of the particles is doubled and the distance between them is also doubled, then the force will be OF/4. OF/2. OF 0 2F Question 30 1 pts Charge carriers in a metal are electrons rather than...
Note: Students must show all the work to get full creait. No formula sheet is needed. Each question is 20 points Four point charges “q” are located at the corner of a square of side “a" meter. All charges are negative except the one located at the origin. Find: (a) the magnitude and (b) the direction of the net force on the positive charge. 1)
Four questions. Please answer with all work shown so I can learn the methods. Thanks (1)Two 2 cm-diameter disks spaced 2.187 mm apart form a parallel-plate capacitor. The electric field between the disks is 464,475.983 V/m. An electron is launched from the negative plate. It strikes the positive plate at a speed of 29,140,951.095 m/s. What was the electron's speed as it left the negative plate? (2)Two equally charged, 3.549 g spheres are placed with 2.925 cm between their centers. When...

Chapter 18, Problem 33 Your answer is partially correct. Try again. Four point charges have the same magnitude of 2.6 × 10-12 C and are fixed to the corners of a square that is 4.5 cm on a side. Three of the charges are positive and one is negative. Determine the magnitude of the net electric field that exists at the center of the square.
