no,not at all.When a charged electron came near to sphere,sphere get not charged but polarity came inside it due to mutual induction.
in plum pudding model why thomson has considered electrons embedded in positively charged sphere?
touch it with a charged object....
When a negatively charged rod touches the sphere of the electroscope, negative sharge spreads throughout the metal. Since the leaves are both negatively charged, the free ends repel and move away from each other. When a positvely rod touchs the sphere, negative charges move toward the sphere, causing the leaves to be positively charged. hope this helps :)
The electric FIELD inside a charged hollow CONDUCTOR is zero.
It is the proton.It has a possitive charge.
sphere
Since a sphere is round it is a shape without a face.
It is not possible to make a ordinary conductor hold it's charge permanently.But you can make a ordinary conductor(e.g.,)a wire to hold charge for a short period.This is because a charge stored in a conductor leaks to the surroundings due to ionisation of air. But it is possible to charge a conductor like a copper sphere. for this the copper sphere is first connected to ground and a negatively charged ebonite rod near it.the copper sphere becomes positive as the negative charges in it flow to the ground.the sphere is disconnected from ground and the ebonite rod is taken away.now the copper sphere holds positive charge. note: it is easy to charge an ebonite rod by rubbing it with fur.
no.
The n-sphere is denoted Sn. It is an example of a compact topological manifold without boundary.
in spherical capacitor two concentric sphere are taken of different radii. one is charged uniformly and placed inside other of greater radii. due to electric induction negative charge come at inner part of second sphere and positive charge come at outer sphere. to vanish this charge we earthed it. only negative charge remains on inner surface which decrease potential of first charged sphere and increase capacity.
