The positive charge moves in the direction of the line of the electrostatic field strength. What is the sign of the field work? How does the potential energy of a charge change – increases or decreases?
A positive charge is acted upon by a force from the electric field, the direction of which coincides with the direction of the electric field, therefore the work of the field is positive. The potential energy of the charge decreases.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
