A charged rod P attracts rod R whereas P repels another charged rod Q.What type of force is developed between Q and R ?

why does a charged glass rod attract a piece of paper?

Explain why a charged calloon is repelled by another charged balloon whereas an uncharged balloon is attracted by another balloon ?

An ebonite rod is rubbed with fur/wool. What type of charges do they acquire?

A thin metallic spherical shell of radius R carries a charge Q on its surface. A point charge Q/2 is placed at its centre C and another charge +2Q outside the shell at a distance r from the centre as shown in figure. Find the force on the charge at the centre of shell and at point A.

A thin metallic spherical shell of radius R carries a charge Q on its surface. A point charge Q/2 is placed at its centre C and another charge +2Q outside the shell at a distance r from the centre as shown in figure. Find the electric flux through the shell.

True or False A charged glass rod attracts a charged plastic straw.

If a point charge be rotated in a circle of radius r around a charge q. what will be the work done?

Frictional electricity The electricity developed in bodies when they are rubbed with each other is called frictional electricity. There are two kinds of charges, namely positive and negative. Like charges repel each other and unlike charges attract each other. when a glass rod is rubbed with silk cloth, glass rod becomes positively charged are silk acquires the same amount of negative charge. the concept of positive and negatice charges was introduced by Benjamin Franklin. The charge is always quantised and conserved in a system. The number of electrons for one coulomb of charge is
