Answer:
if you are trying to figure out if it is right. I believe it is right (the answer) but trust your instincts go for it.
Explanation:
The charge on sphere A is -3 × 10⁻⁷C.
According to the question, there are two identical spheres, sphere A and sphere B with charges
q₁= -1.6 × 10⁻⁶C , and
q₂=+1.0 × 10⁻⁶ C respectively separated by a distance of 2m.
Now, the charges are brought in contact with each other. So the total charge on both the spheres when they are in contact would be the sum of the two charges, that is:
q = q₁ + q₂
q = -1.6 × 10⁻⁶C + 1.0 × 10⁻⁶ C
q = -0.6 × 10⁻⁶C, or
q = -6 × 10⁻⁷C
Since the two spheres are identical, when they are separated from each other, the charge is distributed equally on both of them. So, the charge on each sphere is :
Q = q/2
Q = (-6 × 10⁻⁷C)/2
Q = -3 × 10⁻⁷C
