Question
1. Electric field inside a hollow metallic charged sphere (a) increases towards the center. (b) is zero. (c) is none of the other options. (d) depends on the total charge of the sphere. (e) decreases towards the center (a) becomes infinite. (b) remains unchanged. (c) increases. (d) decreases. (e) reduces to zero. inserted in between the plates. The dielectric constant of the material is x 5. What is the new electric Seld Jafter inserting 2. When a dielectric material is placed in an electric field, the field strength 3. A constant voltage source (a battery) is kept connected to a parallel plate capacitor before and after a dielectng material is the dielectric) when compared to the original feld before inserting tbe dielectric? (a) (1/5) times of the original one. (b) 5 times larger than the original one () (1/25) rimes ofi the original one. (d) 25 times larger than the original one. (e) The same as the original one.Explanation / Answer
1, Electric field inside mettalic conductor will be zero. option (a) is correct
2, When a dielectric placed inside electric field,the net electric field decreases due polarisation inside dielectric.option(d) is correct.
3,If constant voltage source is connected during insertion of dielectric, voltage remains constant while charge on capacitor changes.electric field will be constant option(e) is correct
