Two metallic spheres having same shape and size, but one of Cu and other of Al, are both placed in an identical electric field. In which metallic sphere will more charge be induced?

Answer:
As aluminium and copper are metals, their mobile electrons move under the influence of the external field until they reach the surface of the metal and collect there. External electric fields induce surface changes on metal objects that exactly cancel the field within. Since the field applied is same in both case, the induced charge will be the same.
Hence, the magnitude of induced charge in the aluminium will be the same as that of copper.

Answer:
None will have more charge. Both spheres will have the same amount of charge.
Explanation:Since the field applied in both cases is same and both are metallic conductors, the induced charge will be the same.
