Choose the correct options from the following.

Two objects are attracted to each other. This attraction could be caused by :

I. Magnetic force
II. Electrostatic force
III. Gravitational force

• Magnetic force can be attractive or repulsive. When two like poles of a magnet come close to each other, the magnetic force is repulsive and when two unlike poles come close to each other, the magnetic force is attractive.
• The electrostatic force is exerted between two charged particles. When the particles have similar charges, they repel each other and when the particles have opposite charges, they attract each other.
• Gravitational force is an attractive force exerted between any two objects having some mass.
• Therefore, if two objects are attracted to each other the attraction could be caused by either gravitational force, magnetic force or electrostatic force.

Therefore, 'I, II and III' is the correct response.
