A charge q is located at the centre of a cube. The electric flux through any face is
(2) 4 q6(4 0)
As per Gauss's law, total flux through the closed cube = q 0
∵ The charge is at the centre, all six faces are symmetric.
⇒ Flux through one face = q6 0
⇒ q6 0 = 4 q6(4 0)
Answer: (2)
An electron is moving round the nucleus of a hydrogen atom in a circular orbit of radius r. The Coulomb force F between the two is
A dipole of dipole moment p is placed in uniform electric field E then torque acting on it is given by
A charge Q is placed at the centre of a cube, the flux coming out from each face will be
A charge Q is situated at the corner of a cube, the electric flux passed through all the six faces of the cube is
Electric field at centre O of semicircle of radius a having linear charge density is given as [figure]
