Consider a conductor with a spherical cavity in it. A point charge q_(0) is placed at the centre of cavity and a point charge Q is placed outside conductor. Statement-1: Total charge induced on cavity wall is equal and opposite to the charge inside Statement-2: If cavity is surrounded by a Gaussian surface, where all parts of Gaussian surface are located inside the conductor, ointvec(E)dvec(A)=0 hence q_(induceed)=-q_(0)

Answer»

STATEMENT-1 is true, statement-2 is true and statement-2 is correct EXPLANATION for statement-1.
Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1.
Statement-1 is true, statement-2 is false.
Statement -1 is false, statement -2 is true.
