In figure Which charges are positive?

Fig. shows the electric field lines arround three point charges A, B and C. Which charges are positive?

In figure Which charge has the largest magnitude? Why?

Can there be potential difference between two adjacent conductors which carry the same positive charge?

Which charge is present on protons ?

A charged particle enters a uniform magnetic field experience an upward force as indicated in the figure. What is the charge sign on this particle?

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
