How would you represent the electric field due to a point charge situated at infinity?

Find an expression for electric field intensity due to a point charges.

What should be the value of electric field due to a uniformly charged plane lamina?

Read the statement carefully and write 'Yes' for correct statements and 'No' for wrong statements : In an electric field due to an isolated point charge the electric potential is a point function.

Define electric flux. Give its SI unit. Using Gauss. law, deduce an expression for the electric field due to a uniformly charged spherical conducting shell of radius R at a point inside the shell

Define electric flux. Give its SI unit. Using Gauss. law, deduce an expression for the electric field due to a uniformly charged spherical conducting shell of radius R at a point outside

From the concept of potential gradient find the expression of the electric field intensity at a point in the field of an isolated point charge.

What is meant by the statement, ''the electric field of a point charge has spherical symmetry, whereas that of an electric dipole is cylindrically symmetric'' ?
