Electric Charge...

A charge of magnitude $$3e$$ and mass $$2m$$ is moving in an electric field $$E$$. The acceleration imparted to the charge is 

A charge $$Q$$ is placed at the center of a square. If electric field intensity due to the charge at the corners of the square is $$ E_1 $$ and the intensity at the mid point of the side square is $$ E_2 $$ then the ratio of $$ \dfrac { E_ 1 }{ E_ 2 }$$ will be

A hemispherical surface of radius R is kept in a uniform electric field E as shown in figure. The flux through the curved surface is:

A point charge $$Q$$ is placed at the centre of a circular wire of radius $$R$$ having charge $$q$$. The force of electrostatic interaction between point charge and the wire is:

Two charges Q and -2Q are placed at some distance. the locus of points in the plane of the charges where the potential is zero will be

The electric potential is directly proportional to from the region. The intensity of electric field  

The tangent at any point of  field line gives the direction of

Under the influence of the Coulomb field of charge $$+Q$$, a charge $$-q$$ is moving around it in an elliptical orbit. Find out the correct statements.

A charge Q is placed a the corner of a cube. The electric flux through all the six faces of the tube is 

A hollow cylinder has a charge q coulomb within it. If f the electric flux in units of volmeter associated with the curved surface B , the flx linked with the plane surface A in units of V-m will be :
