Why does electric field of a point charge extend upto infinity?

Expert Answer:

The electric field lines orginate from a positive charge and go on till the negative charge. For a point charge, electric field will originate from it and move away from it in search of a negative charge to terminate. But, since there is just one point charge, it will not find negative charge and hence the field lines will never terminate but instead extend till infinity.
