Question
In the figure above, a neutral and unpolarizable object at position 1 is let go from rest. Describe the object's motion.
a) It moves to the right at constant speed.
b) It accelerates to the right.
c) It accelerates to the left.
d) It moves to the left at constant speed.
e) It remains at the same position.
Explanation / Answer
It will remain at the same position.
As no velocity is given to the object and also there is no external force acting on object. So it won't experience any motion.
Here net force is zero because force on neutral particle in uniform electric field is zero. Here charge are arranged symmetrically. So electric field is constant.
