Class 10 Electricity - Methods of charging

Class 10 polynomial

The electric force experienced by a charge of 5xx10^(-6) C is 25xx10^(-3) N . Find the magnitude of the electric field at that position of the charge due to the source charges.

Total electric force on an electric dipole placed in an electric field of a point charge is :

In which method electric current is created for capturing fishes?

10C and 20C are separated by a distance d. If the electric field at the location of a charge 10C is vec(E ) , the field at the location of 20C is

Electrical force between two point charge is 200N , if we increase 10% charge on one of the charge and and decrease 10% charge on other then electrical force between them for the same direction becomes.

If number of electric lines of force fro charge q are 10, then find out number of electric lines of force from 2q charge.

The electric charges are distributed in a small volume. The flux of the electric field through a spherica surface of radius 10 cm surrounding the total charge is 20 V - m . The flux over a concentric sphere of radius 20 cm will be

The electric intensity due to a dipole of length 10 cm and having a charge of 500 muC , at a point on the axis at a distance 20 cm from one of the charges in air is
