In electrostatics, charges of the same sign repel and charges of different signs attract.
If we apply this to our case, we have that part A and C repel each other, therefore they have the same type of charge.
Also part A and C repel each other, therefore they have the same type of charge.
If we use the transitive property of mathematics, pieces A and B must also have the same type of charges
Answer:
80m
Explanation:
u=20,R=?,sin theta=1,g=10
R=u²sin2theta/g
R=20²x2/10
R=400x2=800/10
R=80m
