A positively charged particle placed next to a negatively charged object will move towards it due to the electrostatic force of attraction. This is consistent with Coulomb's law, which states that unlike charges attract, and is demonstrated by the direction of electric field lines.
If a positively charged particle is placed next to a negatively charged object, the positively charged particle will move towards the negatively charged object. This movement is due to the electrostatic force of attraction, which operates between two charges of opposite signs, as described by Coulomb's law. This law states that unlike charges attract each other. The extent of this attraction is proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.
In the context of electric field lines, which demonstrate the direction a positive test charge would move, the lines point from the positive charge towards the negative charge. Therefore, when placed within such a field, the positively charged particle will experience a force in the direction of these field lines, leading to its motion towards the negatively charged object.
