Study of the photoelectric effect led to important steps in understanding the quantum nature of light and electrons and influenced the formation of the concept of wave-particle duality. The photoelectric effect is also widely used to investigate electron energy levels in matter.
F=ma
Force=mass*acceleration
So plug in the values
Hint: the force would be measured in newtons
Answer:
they would repel each other
Explanation:
they have gained the same charge
