Question

Please provide me full solution:

(1) A charge q1= -7.8 C is 3.7 m from a charge q2= -7 C. What is the magnitude of the electrostatic force on q1?

Answer:

(2)A 10 ?C charge is placed at the origin. An identical charge is placed 9.8 m from the origin on the x axis. A third identical charge is placed 9.8 m from the origin on the y axis. What is the magnitude of the net electrostatic force on the charge at the origin?

(Don't enter a sign for your force; just the magnitude)

Answer:

(3) A particle with a charge of -9 x 10-6C and a mass of 13 g moves uniformly with a speed of 4.6 m/s in a circular orbit around a stationary particle of charge 1 x 10-6C. Calculate the radius of the orbit.

(Careful of your units!)

Answer:

(4) Two identical charges, 5.5 m apart, exert forces on each other of 8.2 N on each other. What is the magnitude of the charges?

( 5) A thin spherical shell has a radius of 2.2 m. If charge is distributed uniformly throughout the surface of the shell with a surface density of ? = 0.92 C/m2, find the total charge on the sphere.

(6) A total charge of 8.7 C is distributed uniformly throughout a 8.3 m radius non-conducting sphere. Calculate the volume charge density.

Enter your units as C/m^3
