What ??! No, no, no. It's not so negligible. It will have an effect, certainly. C = ε°A / (d - t + t/εr) = ε°A / (d - d/4 + d/4εr) = ε°A / (3d/4 - d/4εr).

No effect, because slab thickness will be negligible which doesn't effect capacitance

Raj Singh 3 years, 2 months ago

By using the method of friction, positive charge is developed on one of the bodies and negative charge on the other. When these two bodies are brought close, they attract. Some objects have tendency to gain positive charge (example glass and ebonite rod) while some objects have the tendency to gain negative charge(example silk).
