A solid conducting sphere, having a charge `Q`, is surrounded by an unchanged conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be `V`. If the shell is now given a change of `-4Q`, the new potential difference between the same tow surface is :
A solid conducting sphere, having a charge Q, is surrounded by an uncharged conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V. If the shell is now given a charge of -4 Q, the new potential difference between the same two surfaces
A solid conducting sphere having a charge Q is surrounded by an uncharged concentric conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V. If the shell is now given a charge of -3Q , the new potential difference between the same two surfaces is :
A conducting shell S_1 having a charge Q is surrounded by an uncharged concentric conducting spherical shell S_2 . Let the potential difference between S_1 and that S_2 be V. If the shell S_2 is now given a charge -3Q , the new potential difference between the same two shells is
A conducting sphere is enclosed by a hollow conducting shell. Initially the inner sphere has a charge Q while the outer one is uncharged. The potential difference between the two spherical surface is found to be V. later on the outer shell is given a charge -4Q. The new potential difference between the two surfaces is : (A) V (B) -V (C) -2V (D) 2V
In the given figure there are two concentric shells find potential difference between spheres.
A conducting sphere carrying charge Q is surrounded by a spherical conducting shell. a. What is the net charge on the inner surface of the shell? b. Another charge q is placed outside the shell. Now, what is the net charge on the inner surface of the shell? c. If q is moved to a position between the shell and the sphere, what is the net charge on the inner surface of the shell? d. Are your answer valid if the sphere and shell are not concentric?
Two hollow concentric non-conducting spheres of radius the a and b (a gt b) contain charges Q_(a) and Q_(b) respectively. Prove that potential difference between the two spheres is independent of charge on outer sphere. If outer sphere is given an extra charge, is there any change in potential difference ?
