If the mass of a proton is

We have three identical metallic spheres A, B, C. Initially sphere A is charged with charge 4Q, while B and C are neutral. First, sphere A is brought into contact with sphere B and then separated from it. After that, sphere A is brought into contact with sphere C and then separated from it. Finally, sphere A is brought into contact with sphere B again, and then separated from it. What is the final charge of sphere A

A 20.0×20.0 cm horizontal metal plane is uniformly charged to +75.6 nC. What is the electric field strength 8.60 mm above the center of the electrode?

Which of the following statements about Electric Field Lines due to a charge arrangement is not correct?
