Exercise-1

An uncharged conductor $A$ is brought close to another positive charged conductor $B,$ then the charge on $B$

Which of the following represents the correct graph for electric field intensity and the distance $r$ from the centre of a hollow charged metal sphere or solid metallic conductor of radius $R:$

The figure shows a thick metallic sphere. If it is given a charge $+Q,$ then an electric field will be present in the region

An uncharged sphere of metal is placed in a uniform electric field produced by two large conducting parallel plates having equal and opposite charges, then lines of force look like

Figure shows a closed surface which intersects a conducting sphere. If a positive charge is placed at the point $P,$ the flux of the electric field through the closed surface

A charge $q$ is placed at the centre of a conducting spherical shell of radius $R,$ which is given a charge $Q.$ An external charge $Q\text{'}$ is also present at distance $R\text{'} \left(R\text{'}>R\right)$ from $q$. 
[ where $r$ is the distance of the point from $q$]

Two small conductors $A$ and $B$ are given charges $q_1$ and $q_2$ respectively. Now they are placed inside a hollow metallic conductor ($C$) carrying a charge $Q.$ If all the three conductors $A, B$ and $C$ are connected by conducting wires as shown, the charges on $A, B$ and $C$ will be respectively:

Some charge is being given to a conductor then its potential is:
