Solution:
The point midway between the two charges is located 15.0 cm from one charge and 15.0 from the other charge. The electric field generated by each of the charges is
where
ke is the Coulomb's constant
Q is the value of the charge
r is the distance of the point at which we calculate the field from the charge (so, in this problem, r=15.0 cm=0.15 m).
Let's calculate the electric field generated by the first charge:
While the electric field generated by the second charge is
Both charges are positive, this means that both electric fields are directed toward the charge. Therefore, at the point midway between the two charges the two electric fields have opposite direction, so the total electric field at that point is given by the difference between the two fields:

Answer:
Negative
Positive
Explanation:
When a positive charge balloon is brought near the neutral metal can, the positive charge in the ballon, delocalization and arrangement of like charges occurs. The positive charge then flow to the an end while the negative charges flows to the other end.
Thus, after being touched, the charge on the can is negative.
And, If not touched, the charge on the ballon remains positive.
