a. Explain the meaning of the statement 'electric charge of a body is quantised'.
b. Why can one ignore quantisation of electric charge when dealing with macroscopic i.e., large scale charges?

The material through which electric charge can flow easily is ………………. .

An electric charge is placed at the centre of a cube of side a. The electric flux through one of its foces will be

The total electric flux emanating from a closed surface enclosing an alpha -particle (e- electronic charge) is

Electric charge can be transferred from a charged object to another through _____.

The centre of mass is defined as vecR=1/Msum_im_ivecr_i . Suppose we define centre of charge as vecR_c=1/Qsum_iq_Ivecr_i where q_i represents the ith charge placed at vecr_i and Q is the total charge of the sytem a. Can a centre of charge of two charge system be outside the line segment joining the charges? b. If all the charges of a system are in X-Y plane? c. If all the charges of a system lie in a cube, is it necessary that the centre of charge be in the cube?

When the separation between two charges is increased, the electric potential energy of the charges
