Answer: D. Acceleration of Object A is twice of that of the acceleration of Object B.
Answer:
e. all three objects possess charges of the same sign.
Explanation:
We know that objects with same polarity will repel each other while objects with opposite polarity will attract each other. Here objects A and B repel each other which means they possess the charge of same polarity. Objects B and C also repel each other which means that they also possess the same polarity (sign).
This means that A and C will also repel each other. All the three objects possess the charge with same polarity.
If you count Pluto, then Pluto. But if you dont, then its Neptune. This is because of the gravitational pull of the sun. Neptune/Pluto is the farthest so it has the least affect from the gravitational pull.
