Consider three metal spheres, A, B and C. A has the same number of electrons and protons. B has 1.88x1020 fewer electrons than protons. C has 1.25x1020 more electrons than protons. a) What is the charge (in MKS units) on each sphere? b) What is the total charge on all of the spheres? Touch A to B and separate them. Then touch B to C and separate them. Finally touch C to A and separate them. c) What is the...
Two tiny spheres have the same mass and carry charges of the same magnitude. The mass of each sphere is 4.98 10-6 kg. The gravitational force that each sphere exerts on the other is balanced by the electric force. (b) Determine the charge magnitude.
3: You have three metal spheres. Spheres A and B'attract each other. Spheres A and C attract each other and spheres B and C attract each other. What is the sign of the net charge on each sphere? For example, your answer might be 2 spheres negative and one sphere neutral or 2 spheres positive and one sphere negative. Explain.
Three identical metal spheres are hung from a ceiling on rigid non-conducting rods. Sphere 1, sphere 2, and sphere 3 have charges 33 muC, -52 muC, and 48 muC, respectively. Each sphere is separated by 17 cm What is the net electric force on the middle sphere due to spheres 1 and 3? (Enter the magnitude only.) How do you calculate the electric force? If the spheres all lay along the same line, how do you calculate the net force?...
Three charged spheres are at rest in a plane as shown in the
figure below. Spheres A and B are fixed, but sphere C, of unknown
mass m, is attached to the ceiling by a lightweight
thread. The tension in the string is 0.130 N. Spheres A and B have
charges
qA = 47.0 nC
and
qB = −47.0 nC.
What charge is carried by sphere C?

Two uniform solid spheres have the same mass, 1.65 kg, but one has a radius of 0.256 m while the other has a radius of 0.844 m. For each of the spheres, find the torque required to bring the sphere from rest to an angular velocity of 357 rad/s in 10.5 s. Each sphere rotates about an axis through its center. a)Torque on sphere with the smaller radius. b)Torque on sphere with the larger radius. c)For each sphere, what force...
Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of -10q. Sphere B carries a charge of +9q. Sphere C carries no net charge. Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it. Last, sphere C is touched to sphere B and separated from it. For the following questions, express your answers in terms of q. (a) How much charge ends up...
Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of -6q. Sphere B carries a charge of +5q. Sphere C carries no net charge. Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it. Last, sphere C is touched to sphere B and separated from it. For the following questions, express your answers in terms of q. (a) How much charge ends up...
Rolling and Torque Two spheres of the same mass are positioned on a 100 meter ramp with at 20 degree incline. Both spheres have a radius or 5 m and mass of 1000 kg (HUGE SPHERES, think Indiana Jones). The difference is how the mass is distributed. One sphere is completely solid with mass equally distributed throughout it. The second mass has all of its mass distributed at the edge of its radius in a thin shell. So, one...
Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of +8q. Sphere B carries a charge of -q. Sphere C carries no net charge. Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it. Lastly, sphere C is touched to sphere B and separated from it. (a) What is the ratio of the final charge on sphere C to q? What is the...
