Question

3. A point charge +Q is placed next to a hollow, spherical conducting shell. A second point charge +q placed at the center of the cavity. A . On the diagram, sketch the net electric field in the space within the shell. Explain. b. Would the +q charge experience a force? If so, in which direction? Explain why or why not. The +Q charge is now moved closer to the shell as shown- c. After a new stable distribution is reached, sketch the net electric field in the space within the shell. Explain. d. Suppose you were inside the shell. Could you tell that the +Q charge had changed positions? Explain why or why not. The +q charge is now moved off - center, toward the + Q charge as shown. e. Would this movement affect the + Q charge? Explain why or why not. f. Based on your answers above, does any change to the charge distributions either inside or outside of the sphere affect the electric field in the other region? Explain.

Explanation / Answer

a) electric field will be radially outwards from +q to shell.

b) no +q will not experience any force.

because field inside cavity was zero.

c) it will be same as it was in a).

d) No, because there is no electric field becuase of shell or outer +Q charge inside cavity.

e) No, it will no affect as conducting shell will redistribute charge inside it to nullify the effect.

f) No.
