Question:
a. Define electric field strength.
b. Two charged conducting spheres, each of radius 1.0 cm, are placed with their centres 10 cm apart, as shown.
Sphere A carries a charge of +2.0 × 10−9 C.
The graph shows how the electric field strength between the two spheres varies with distance x.
i. Determine the field strength 5.0 cm from the centre of sphere A
ii. Use your result to i to calculate the charge on sphere B.
c i. Sphere B is now removed. Calculate the potential at the surface of sphere A.
ii. Suggest and explain how the potential at the surface of sphere A would compare before and after sphere B was removed.
