The radius of a spherical shell is R. Because inside the conducting charge sphere, an electric field is zero. So, the electric field at a distance R/2 from the centre of the sphere will be zero.

7. A conducting sphere of radius 1 cm is surrounded by a conducting spherical shell of inner radius 3 cm and outer radius 4cm. If the electric field at r=2 cm is going outwards with magnitude 300 V/cm and at r=5 cm is also going outwards with magnitude 300 V/cm. What is the net charge on conducting spherical shell? Solution: Make a Gauss ...

Putting "charge is quantized" in terms of an equation, we say: q = n e q is the symbol used to represent charge, while n is a positive or negative integer, and e is the electronic charge, 1.60 x 10-19 Coulombs. The Law of Conservation of Charge. The Law of conservation of charge states that the net charge of an isolated system remains constant.

THE PROBLEM Consider a hollow metal sphere of inner radius r-16.8 cm and outer radius R-20.4 cm. The sphere is not charged, but there is a point charge of q-253 nC at the centre of the sphere (a) Calculate the charge density on the sphere's outer surface (b) Calculate the electric field strength at the sphere's outer surface PAPER SOLUTION ...

Jun 09, 2019 · Ans. (d) When a positive point charge is placed outside a conducting sphere, a rearrangement of charge take place on the surface.But the total charge on the sphere is zero as no charge has left or entered the sphere. 21.A long, hollow conducting cylinder is kept coaxially inside another long, hollow conducting cylinder of larger radius. Both ...

A hollow conducting charged sphere of radius 10 cm is connected to the positive terminal of an EHT supply which is at 4000v. (a) What is the charge stored on the sphere (think of the surface as an equipotentialat 4000 V created by a point charge at the centre of the sphere)? (b) At what distance from the sphere's surface is the potential 200V?
