What are positive and negative charges? How are these produced?

An action potential in the nerve fibre is produced when positive and negative charges on the outside and the inside of the axon membrane are reversed,because

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. A body can be negatively charged by

Define acceleration .What are positive and negative accelerations?

What are e.m. waves?How are they produced?

Consider a coin, It is electrically neutral and contains equal amounts of positive and negative charge of magnitude 34.8 kC . Suppose that these equal charages were concentrated two point charges separated by 100 m(-length of a long building),find the force on each such point charge in this case. What do you conclude from these results?
