A metal sphere is given a charge by induction. This happens in four stages, W, X, Y and Z. W: a charged rod is moved close to the sphere X: the sphere is connected to earth Y: the charged rod is moved away from the sphere Z: the earth connection is then removed What is the correct sequence for these four stages?
- AW → X → Y → Z
- BW → X → Z → Y
- CZ → W → X → Y
- DX → Z → W → Y
