Question

select the true statements about electric interactions.
choose 2 answers:
a matter contains many small particles with electric
charge.

b electric forces are always repulsive.

c two objects can exert electric forces on each other
without being in contact.

d there is only one type of electric charge.

Explanation:

• Option A: Matter is made of particles like protons (positive charge), electrons (negative charge), so it contains many charged particles. This is true.
• Option B: Electric forces can be attractive (opposite charges) or repulsive (like charges), so "always repulsive" is false.
• Option C: Electric forces are non - contact forces (e.g., charged objects can attract/repel from a distance), so two objects can exert electric forces without contact. This is true.
• Option D: There are two types of electric charge: positive and negative, so "only one type" is false.

Answer:

A. Matter contains many small particles with electric charge.
C. Two objects can exert electric forces on each other without being in contact.
